The truth is somewhere in the middle; From weekend plinkers to elite rifle competitors, understanding the basics of muzzle velocity is an essential part of gun ownership and marksmanship. This length ratio maximizes the projectile velocity. There’s lots of discussion about how barrel length can affect velocity. noun. Projectile speed through air depends on a number of factors such as barometric pressure, humidity, air temperature And like I said in the graphic with the chart, the precision is 0.25 MOA, the muzzle velocity SD is 10fps, and the wind confidence is within 2.5mph 95% of the time (meaning the SD is 1/2 that). Interior ballistics, the science of how powder burns, gases expand, pressure builds, and bullets travel from brass to bore is incredibly complexand I don't want to trivialize it. Video shows what muzzle velocity means. First off, what is ‘muzzle energy’? For Each Round, Two Measurements Of The Velocity Were Recorded Using Two Different Measuring Devices, Resulting In The Following Data. noun. So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. The same principle applies to bullets. For Each Round, Two Measurements Of The Velocity Were Recorded Using Two Different Measuring Devices, Resulting In The Following Data. General abbreviations used below are: MV (muzzle velocity), ME (muzzle energy), V (velocity), E (energy), yds (yards), Wb (weight of bullet). If he hits you, it’s going to hurt. The pressurized gas was then released to a secondary piston, which traveled forward into a shock-absorbing "pillow", transferring the energy from the piston to the projectile on the other side of the pillow. Energy at the target, which is considered critical to terminal performance, is enhanced when a bullet is traveling at a higher speed. Wikipedia has a pretty good description and discussion of it. Muzzle velocity is the speed a projectile has at the moment it leaves the muzzle of the gun. Longer barrels provide more opportunity to rotate the bullet before it leaves the gun. Think of throwing a baseball: when you throw the ball with a light, slow lob, it will drop quickly and its trajectory will look more like an arch. In case anyone has the same question that I did, I found the link to the manual from the launcher and from the manual I found this: Damage - Damage done by each non-critical shot. Muzzle-velocity definitions The velocity of a projectile as it leaves the muzzle of a firearm: expressed in feet per second. As you can see, there is a huge difference in bullet velocities from caliber to caliber. velocity of a discharged projectile at the muzzle of a firearm These overcome the limitations noted above. The 5.7×28mm SS90 cartridge was discontinued, and replaced, in 1993, with the 5.7×28mm SS190. The higher, the more likely you don't have to compensate for travel distance. the speed of a projectile, usually expressed in feet or meters per second, as it leaves the muzzle of a gun. Loss of speed is tied to a concept of “ballistic coefficient,”. It actually doesn't do as much as you'd think. Velocity matters in terms of physical recoil; F=MA, after all...but it's less of a factor than you'd think. While traditional cartridges cannot generally achieve a Lunar escape velocity (approximately 2,300 m/s (7,500 ft/s)) or higher due to modern limitations of action and propellant, a 1 gram (15.4324 grains) projectile was accelerated to velocities exceeding 9,000 m/s (30,000 ft/s) at Sandia National Laboratories in 1994. It doesn't really matter if you're playing on lower difficulties, since the bullet goes in a straight line according to the tooltips. The United States Army defines different categories of muzzle velocity for different classes of weapons:[12], https://www.thefreedictionary.com/muzzle+velocity, "Fastest Gun on Earth: Goals Go Beyond Planet", https://en.wikipedia.org/w/index.php?title=Muzzle_velocity&oldid=994986811, Creative Commons Attribution-ShareAlike License, Between 914 m/s (3,000 ft/s) and 1,067 m/s (3,500 ft/s), Between 472 m/s (1,550 ft/s) and 1,021 m/s (3,350 ft/s), Between 1,067 m/s (3,500 ft/s) and 1,524 m/s (5,000 ft/s), This page was last edited on 18 December 2020, at 16:14. Every single bullet, whether it’s a full-metal jacket, hollow point, or soft nose, can be measured in muzzle velocity. This is repeated in Winchester’s Power Max cartridges. L ee) The accompanying data represent the muzzle velocity (in meters per second) of rounds fired from a 155-mm gun 793.8 793.1 1792.4 1794.0 791.4 - 792.4 791.7 792.3 789.6 7944 (a) Compute the sample mean and median muzzle velocity (b) Compute the range, sample variance, and sample standard deviation (a) The sample mean muzzle velocity is meters per second. Max Zoom - The maximum zoom level of the attached scope. Muzzle velocity, however, is not always a fair comparison, as different projectiles have different purposes and downrange performance. Muzzle velocity is the speed a projectile has at the moment it leaves the muzzle of the gun. Rate of Fire - Higher rate of fire means more rounds fired over the Velocity in feet per second. Longer barrels give the propellant force more time to work on propelling the bullet. Higher velocities will be less affected by gravity and wind. the muzzle). Muzzle velocity is determined by many factors: caliber of your firearm, size and weight of … Projectile speed through air depends on a number of factors such as barometric pressure, humidity, air temperature Translate Muzzle. Hitmarkers are still instant for the most part, but some long range shots need to be led a bit. It is often used as a rough indication of the destructive potential of a given firearm or load. Faster bullets are also better for terminal performance. In other words, velocity does affect recoil but an increase in velocity has less of an effect th… This means the projectile becomes a strictly kinetic weapon. Enrich your vocabulary with the English Definition dictionary See more. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to 8,500 m/s (28,000 ft/s).[6]. Explosive propellant, stored in large quantities, is susceptible to explosion. To give you an idea of muzzle velocity statistics, here are a few listed velocities for specific products in some of the most popular cartridges: Ballistic coefficient is a measurement of a projectile’s ability to resist air drag. Complete Parts (a) Through (d) Below Observation 1 … Is muzzle velocity something you need to be concerned about? A slower-burning propellant needs a longer barrel to finish its burn before leaving, but conversely can use a heavier projectile. The MVR of choice was the MVR-700 SC (Sub-Compact) from Danish radar specialist Weibel. Muzzle velocity variations for a high-speed rifle projectile show more effect on POI because of the changing drag as a function of velocity. The velocity of a discharged projectile at the muzzle of a firearm.. Muzzle velocity Meaning. Muzzle Velocity - The velocity of bullets fired. Muzzle-velocity definitions The velocity of a projectile as it leaves the muzzle of a firearm: expressed in feet per second. Stability - The amount of sway while looking through the scope. This greatly increases the muzzle velocity. General abbreviations used below are: MV (muzzle velocity), ME (muzzle energy), V (velocity), E (energy), yds (yards), Wb (weight of bullet). For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. The three-sigma rule for normal distribution for a sample size under 30 works fine for interpreting SD when chronographing loads. The first problem is airgun hunting. Muzzle 100 Y 200 Y 300 Y 400 Y 500 Y; 2910: 2616: 2340: 2081: 1839: 1619: Energy in Foot Pounds. Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the shot. In the table below bullet weight is given in grains, velocity is given in feet per second (fps) and energy is given in foot pounds (ft lb). Projectile speed through air depends on a number of factors such as barometric pressure, humidity, air temperature and wind speed. ‘The weapon had a muzzle velocity of fifty-five hundred meters per second, and even Karl had to be well-braced to fire it with any degree of accuracy.’. Recoil Dampening - The recoil following each shot. Once it leaves the barrel, the force of the expanding gas ceases to propel the bullet forth. Many factors affect the muzzle velocity such as cartridge power, bullet grain, and barrel length. In a side by side comparison with the .50 BMG (43g), the 15.4324 gr (1 g) titanium round of any caliber released almost 28 times the energy of the .50 BMG, with only a 27% mean loss in momentum. This basically means most values (muzzle velocity) will fall within 3 standard deviations of the mean (avg muzzzle velocity). Velocity matters in terms of physical recoil; F=MA, after all...but it's less of a factor than you'd think. Muzzle velocity is simply a measure of the speed of the projectile the moment it leaves the barrel. (To be fair, felt recoil is more directly connected to muzzle energy, not velocity, but velocity will impact energy.) Muzzle velocity variations for a high-speed rifle projectile show more effect on POI because of the changing drag as a function of velocity. Military the speed of a projectile, usually expressed in feet or meters per second, as it leaves the … : the energy of impact of a bullet at the velocity developed at the muzzle of the piece and calculated according to the formula ME = 1/7000 V 2 ÷ 2g x w where ME represents muzzle energy in foot-pounds, V 2 the square of the muzzle velocity in feet per second, g the acceleration due to gravity, and w the weight of the bullet in grains avoirdupois For those who are t… muzzle velocity definition in English dictionary, muzzle velocity meaning, synonyms, see also . See 5 authoritative translations of Muzzle in Spanish with example sentences, conjugations and audio pronunciations. This experiment is an effort to observe, explore, and learn. This is because larger bullets require more energy to be launched at a high speed. Additionally, the length of the barrel used in testing can have a major impact in the results. First of all, a higher muzzle velocity will mean a straighter trajectory down range. muzzle velocity - WordReference English dictionary, questions, discussion and forums. I haven’t seen these data published recently so here they are. There’s lots of discussion about how barrel length can affect velocity. 24″ is the SAAMI (industry) standard despite the fact that most .223 ammo is probably fired from an 18″ AR-15 barrel. However, if the same linebacker hits you at a sprinting speed of 14 miles per hour, it’s really going to hurt. Two to three milliseconds after the striker hits the primer, pressure has dropped to zero. Measured in feet divided by seconds and represented as fps, muzzle velocity is going to be the fastest immediately after the projectile leaves the barrel. See more. In conventional guns, muzzle velocity is determined by the quantity of the propellant, its quality (in terms of chemical burn speed and expansion), the mass of the projectile, and the length of the barrel. muzzle loaders available. First off, what is ‘muzzle energy’? First, burning gunpowder was used to drive a piston to pressurize hydrogen to 10,000 atm. Different bullets, however, will perform differently when it comes to loss of speed. This article has a ton of ballistic coefficient details but in general, the higher the number, the more aerodynamic it is. There are really two types of gun owners who really want to focus on muzzle velocity. © Copyright Ammotogo.com 2020 All Rights Reserved. Faster bullets are generally more reliable for downrange shooting because they don’t drop nearly as much. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. In other words, velocity does affect recoil but an increase in velocity has less of an effect th… Mostly snipers and marksman rifles, but other guns can do it at mid range if your velocity … muzzle velocities synonyms, muzzle velocities pronunciation, muzzle velocities translation, English dictionary definition of muzzle velocities. L ee) The accompanying data represent the muzzle velocity (in meters per second) of rounds fired from a 155-mm gun 793.8 793.1 1792.4 1794.0 791.4 - 792.4 791.7 792.3 789.6 7944 (a) Compute the sample mean and median muzzle velocity (b) Compute the range, sample variance, and sample standard deviation (a) The sample mean muzzle velocity is meters per second. Rifled barrels have spiral twists carved inside them that spin the bullet so that it remains stable in flight, in the same way an American football thrown in a spiral will fly in a straight, stable manner. One of the important aspects of terminal performance is the transfer of energy. The higher, the more likely you don't have to compensate for travel distance. [2] Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets,[3] to more than 1,200 m/s (3,900 ft/s)[4] in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to 1,700 m/s (5,600 ft/s)[5] for tank guns firing kinetic energy penetrator ammunition. muzzle velocity - the velocity of a projectile as it leaves the muzzle of a gun speed , velocity - distance travelled per unit time Based on WordNet 3.0, Farlex clipart collection. We’re now getting into some fairly heavy physics, but as a shooter, and especially a hunter, you need to remember that a bullet will slow downrange. Most material © 2005, 1997, 1991 by Penguin Random House LLC. Muzzle velocities range from approximately 400 ft/s to 1,200 ft/s in black powder muskets, to more than 4,000 ft/s in modern rifles with high-performance cartridges such as the .220 Swift and .204 Ruger, all the way to 5,700 ft/s for tank guns firing kinetic energy penetrator ammunition. To be precise, 69.27% will be within 1 SD, 95.45% within 2 SD's, & 99.73% within 3 SD's. There is much interest in modernizing naval weaponry by using electrically powered railguns, which shoot projectiles using an electromagnetic pulse. Muzzle velocity is the speed a projectile has at the moment it leaves the muzzle of the gun. [11] While this can be mitigated with safety precautions,[11] railguns eschew the need for such measures altogether. Within a gun, the gaseous pressure created as a result of the combustion process is a limiting factor on projectile velocity. It’ll help keep you consistent and on-target. It is often used as a rough indication of the destructive potential of a given firearm or load. If one examines shot groups on a paper target from a 2-inch (51 mm) barrel, a 4-inch (100 mm) barrel, and a 6-inch (150 mm) barrel, one will observe how the longer barrels produce "tighter" grouping, with bullets landing closer together on the target. Definition of muzzle velocity. Here’s the simple definition: Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. © … It doesn't really matter if you're playing on lower difficulties, since the bullet goes in a straight line according to the tooltips. WordReference Random House Unabridged Dictionary of American English © 2020 muz′zle veloc′ity, [ Ordn.] 200rds – 223 Rem Sierra Prairie Enemy 55gr. How to pronounce, definition audio dictionary. A .22 LR cartridge is approximately three times the mass of the projectile in question. muzzle velocity in American English. It actually doesn't do as much as you'd think. See 5 authoritative translations of Muzzle in Spanish with example sentences, conjugations and audio pronunciations. ‘Adding a silencer to a rifle increases the muzzle velocity.’. In the table below bullet weight is given in grains, velocity is given in feet per second (fps) and energy is given in foot pounds (ft lb). Hard recoil can also impact follow-up shots in self-defense situations, so some recommend slower cartridges as opposed to “hotter” rounds, especially for smaller or weaker gun owners. In most cases, the larger the bullet you have, the slower the velocity. You’ll see a muzzle velocity listed for nearly all ammo, sometimes even right on the box. Question: The Following Data Represent The Muzzle Velocity (in Feet Per Second) Of Rounds Fired From A 15-mm Gun. Complete Parts (a) Through (d) Below Observation 1 … All Free. Muzzle definition, the mouth, or end for discharge, of the barrel of a gun, pistol, etc. The gun operated in two stages. The faster the projectile (either a bullet or a linebacker), the more energy is driven into the target. The Federal 115-grain 9mm ammo has a muzzle velocity of 1,180 fps, while the larger bullet is propelled at 1,000 fps. The more we all know, the better organized and stronger the shooting and hunting community will be. The heavier the bullet and the faster it moves, the higher its muzzle energy and the more damage it will do. The latter is how that force is experienced by the person shooting the gun. Muzzle velocity is dependent on several things; barrel length is just one contributing factor. Define muzzle velocities. One area where muzzle velocity plays less of a role is in recoil. Hope that makes sense! The latter is how that force is experienced by the person shooting the gun. Given a long enough barrel, there would eventually be a point at which friction between the bullet and the barrel, and air resistance, would equal the force of the gas pressure behind it, and from that point, the velocity of the bullet would decrease. : the speed of a projectile at the moment of leaving the muzzle of a gun. A bullet, while moving through its barrel, is being pushed forward by the gas expanding behind it. They are long-distance rifle competitors and long-distance hunters. Translate Muzzle. Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the shot. This is a mathematical tradeoff. muzzle velocity - the velocity of a projectile as it leaves the muzzle of a gun speed , velocity - distance travelled per unit time Based on WordNet 3.0, Farlex clipart collection. 1. the velocity of a projectile as it leaves the muzzle of a gun Familiarity information: MUZZLE VELOCITY used as a noun is very rare. Therefore, if you are using rifle cartridges for long-range hunting, you not only need to be concerned with muzzle velocity, but you should also understand the rated velocity for the distance you to target. Muzzle Velocity – What Is It and Why Does It Matter? Most shooters will find two specific advantages to a higher muzzle velocity, differences that impact how the bullet maintains a trajectory and how the bullet performs when it impacts the target. But if you hurl the ball as fast as you can, like a fastball pitch, it will have a trajectory that is closer to a straight line. Even if your bullet is only traveling an inch, it will lose velocity, as air drag is steadily wearing down momentum. According to Newton’s famous law of equal and opposite reactions, if the bullet is leaving the projectile at a higher speed (which means higher energy), the kick of your rifle against your shoulder or a pistol against your hand will be harder. Faster velocities don t always mean … The 5.7×28mm SS90 cartridge was discontinued, and replaced, in 1993, with the 5.7×28mm SS190. See more. With these railguns, a constant acceleration is provided along the entire length of the device by means of the electromagnetic pulse. BlitzKing Ammo. © … (Technically, the bullet is fastest at the instant the explosion occurs and the bullet is expelled from the cartridge.). A chronograph measures the velocity of your shots giving you valuable information to improve your shooting. Military. Lyman is the company that makes bullet molds- the best bullet molds in my opinion. The former, of course, is an amount of force generated by the gunshot itself. Hope that makes sense! Some high-velocity small arms have muzzle velocities higher than the escape velocities of some Solar System bodies such as Pluto and Ceres, meaning that a bullet fired from such a gun on the surface of the body would leave its gravitational field; however no arms are known with muzzle velocities that can overcome Earth's gravity (and atmosphere) or those of the other planets or the Moon. Because of this drop in speed, a bullet, even if placed on target, may not have the energy and momentum to perform effectively. Muzzle velocity is dependent on several things; barrel length is just one contributing factor. Energy, in most cases, is what is lethal to the target, not momentum.[7]. Enrich your vocabulary with the English Definition dictionary Muzzle velocity is the speed of a projectile the moment it leaves the barrel. Muzzle velocity radars (MVR) have been used by artillery for decades, but are still considered “exotic” when it comes to mortars. For a high-velocity rifle projectile, the drag or BC is very much dependent on velocity. Translation for 'muzzle velocity' in the free English-Danish dictionary and many other Danish translations. Question: The Following Data Represent The Muzzle Velocity (in Feet Per Second) Of Rounds Fired From A 15-mm Gun. Let your fellow shooters know – share this article using the Facebook, Twitter and other social media icons below. Most manufacturers will state muzzle velocity in feet per second (or FPS) in the product specifications, and is even used throughout the products on our website, but there are problems with simply stating velocity. For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. [8] For this reason longer barrels generally provide higher velocities, everything else being equal. Muzzle definition, the mouth, or end for discharge, of the barrel of a gun, pistol, etc. Muzzle velocity is simply a measure of the speed of the projectile the moment it leaves the barrel. As the bullet moves down the bore, however, the propellant's gas pressure behind it diminishes. For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. The biggest difference for a pistol shooter is, of course, the range is generally much shorter. The velocity of a projectile is always fastest when it leaves the barrel. From left to right: .223 Rem ammo next to .308 ammo. The velocity with which a bullet or shell leaves the muzzle of a gun. Muzzle velocity is generally stated in feet per second, or “fps.” However, many European brands are listed in meters per second, which is abbreviated as either “mps” or “m/s.” For consistency, we’ll use fps for the rest of this article like the red-blooded Americans we happen to be! If a bullet is traveling at a faster speed, it will either penetrate deeper, expand better, or both. We’ll use another sports analogy to make this point: think of a linebacker traveling at 6 mph, which is a typical jogging speed. This experiment is an effort to observe, explore, and learn. The heavier the bullet and the faster it moves, the higher its muzzle energy and the more damage it will do. Some cartridges produce a muzzle velocity in excess of the speed of sound and some produce a muzzle velocity below the speed of sound. For example, American Eagle makes 9mm full-metal jacket rounds with 115-grain bullets and 147-grain bullets. If you participate these activities, always want to check the listed muzzle velocity (and downrange velocity) of your ammo. n the velocity of a projectile as it leaves a firearm's muzzle The velocity of a projectile with respect to the muzzle … The former, of course, is an amount of force generated by the gunshot itself. Is a higher muzzle velocity better? Mostly snipers and marksman rifles, but other guns can do it at mid range if your velocity … Muzzle velocity: The speed of the bullet. As such, longer barrels increase the overall precision of the weapon. They can actually see the muzzle velocity of a bullet displayed on their chronograph’s screen, so they know when it’s “fast enough” – usually meaning over 3,000 fps for open-country, big-game rifles. ‘So, instead, the muzzle velocity for a bullet coming out of a gun is typically given in feet per second.’. For instance, Hornady uses a 24″ barrel to test and record muzzle velocities for their 223 ammo. In some instances, the powder may not have even been fully burned in guns with short barrels. As we know, recoil comes in two forms: physical recoil and felt recoil. In 2019, the Danish armed forces were the first to integrate an MVR into a 120 mm mortar system (Cardom 10 from Elbit). The SS190 uses a 2.7 mm (0.11 in) shorter projectile with a weight of 2.0 g (31 grains), which has, when fired from the P90, a muzzle velocity of roughly 715 m/s (2,350 ft/s). Modified entries © 2019 by Penguin … Muzzle velocity definition, the speed of a projectile, usually expressed in feet or meters per second, as it leaves the muzzle of a gun. Consequently, propellant quality and quantity, projectile mass, and barrel length must all be balanced to achieve safety and to optimize performance. The bullet is on its way. Muzzle Velocity - The velocity of bullets fired. As we know, recoil comes in two forms: physical recoil and felt recoil. Velocity in feet per second. The noun MUZZLE VELOCITY has 1 sense: 1. the velocity of a projectile as it leaves the muzzle of a gun Familiarity information: MUZZLE VELOCITY used as a noun is very rare. Muzzle velocity: The speed of the bullet. For those who are t… When a bullet it traveling at a faster rate, it will not drop as quickly. It's more or less what I'd imagined then. Another significant advantage of railguns is not requiring explosive propellant. This may be another indication that future arms developments will take more interest in smaller caliber rounds, especially due to modern limitations such as metal usage, cost, and cartridge design. Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the shot. This article has a ton of ballistic coefficient details, Bill Drill - Rapid, Accurate Follow-Up Shots, El Presidente Drill - Assessing Your Shooting Skills, Choosing the Best Slug Gun for Deer Hunting, .22 Long Rifle Remington Thunderbolt: 1,255, .30-06 Springfield Federal Power-Shok: 2,700, .308 Winchester Super-X Power Point: 2,820, .44-40 Winchester Super-X Soft Point: 1,190, .357 Magnum Hornady Critical Defense: 1,500. It's more or less what I'd imagined then. And like I said in the graphic with the chart, the precision is 0.25 MOA, the muzzle velocity SD is 10fps, and the wind confidence is within 2.5mph 95% of the time (meaning the SD is 1/2 that). With so many differences, it’s essential that you understand how muzzle velocity will impact performance. This mechanism is known as rifling. Some cartridges produce a muzzle velocity in excess of the speed of sound and some produce a muzzle velocity below the speed of sound. There are few people who could claim to be experts on this subject matter and I'm certainly not one of them. Muzzle velocity is the measure of the speed of a projectile as soon as it leaves the barrel of the firearm. Hitmarkers are still instant for the most part, but some long range shots need to be led a bit. There are few people who could claim to be experts on this subject matter and I'm certainly not one of them. This won’t be noticed in smaller, less powerful cartridges, such as the .17 HMR, but it will be noticed in large cartridges such as the .44 Magnum or .50 BMG. For a high-velocity rifle projectile, the drag or BC is very much dependent on velocity. [8] A faster-burning propellant may accelerate a lighter projectile to higher speeds if the same amount of propellant is used. The 150-grain bullet has a muzzle velocity of 2,820, while the 180-grain has a muzzle velocity of 2,620 feet per second. The velocity of a projectile is always fastest when it leaves the barrel. The biggest difference for a pistol shooter is, of course, the range is generally much shorter. This discovery might indicate that future projectile velocities exceeding 1,500 m/s (4,900 ft/s) have to have a charging, gas-operated action that transfers the energy, rather than a system that uses primer, gunpowder, and a fraction of the released gas.
