what does ACP mean in terms of ammunition, and what is the difference in ACP and GAP?
969867
ACP stands for automatic Colt Pistol and GAP stands for Glock automatic Pistol. Colt and Glock are two separate makes of hand pistol. \n\nThe ammunition is for that type of weapon.  \n\n.45GAP ammo typically runs between 19,900 psi and 22,000 psi (slightly under to slightly over the standard pressure 21,000 psi maximum for the .45 ACP). \n\npsi stands for pounds per square inch and represents the force the gun fires with with the ammo indicated.

Ok, ready for the infantry Marine's answer?  Both are a terrible experience that'll make you see how much of your body you can fit in your helmet.  Given the choice, I'd much rather be in a firefight than on the receiving end of artillery.  Arty is very very devastating and the cannons are a couple thousand meters off, so it's not like you can return fire or do much about it.  In a firefight at least you can fight back, and you'll basically know where your enemy is, so you can have something to work off of.  Both are really bad though.

The difference between the 223 and 224 bullets is one thousandth of an inch, you can use 223, but your accuracy may suffer. The .224 is the standard 22 bullet for centerfire(uses a primer) the 223 is a NATO design from overseas.  Just don't mess up a perfectly good 308 playing around with the accelerator toys.

Bullets are either measured in millimeters (mm) or caliber.  This number refers to the diameter of the bullet.  Caliber bullets are measured as a decimal of an inch.  For example, .40 cal = .40 of an inch

Cartridges of the World lists 21 .38 cartridges and 3 .380's.  All use projectiles of approximately the same diameter but varying lengths and weights.  Case lengths, shapes, and rims are all different.

m-16 the ak is more durable but the m-16 has better max effective range, more accurate and higher muzzle velocity and rate of fire. ak47= 7.62mm round rate of fire is 600 rounds a minute muzzle velocity is2350 feet per second and has an effictive range of400m (1312 ft) m-16=5.56 mm round which is a smaller round but...rate of fire is 800 rounds per minute 200 faster than ak 47 muzzle velocity is 3280 feet per second and has a 500 m effective range, so the m-16 shoots faster more accurate and shoots farther

The cartridge, containing the propellant and a shell in one unit, was originally design for the Gattlin gun in about 1860.  This type of ammunition was experimented with for ordnance (the correct generic name for artillery pieces) as soon as the breech loading models were designed.  They did not become common until World War I.  Prior to World War II the cartridges were almost always made of brass.  Steel was used later.

Unhappy.\nHowever there are many different and important factors to keep in mind. The 556 is a small round. Its actually a 22 caliber round.  It is very light weight. Much less then the 7.62x51 (308 winchester). However the 556 is meant to be fired at full auto. The 7.62x51 (by which i will refer to as the 308) is much heavier much more powerful and has too much recoil for full auto. The 308 is still used as a sniper round, even though several others are much better, such as 30-06, or several other (e-mail me and i will tell you why they use the 308) and the 308 is the ammo used for the M240 light machine gun. the 208 is the perfect round for the light machine gun. Say any different and my brother will mix words with you. \nWhatever the government says, the 556 was designed to penetrate soviet body armor. It mushrooms when passing through body armor and actaully has more shock value (due to increased surface area) despite going through the armor. It takes too many hits to take down an opponet and wastes too much ammo. Its really a shame, because there are civial loads of 556 (teachnically 223, because they are on the civilan market) that have much heavier bullets and have far greater stopping power.\n\nthe 6.8 is too dangerous.  Say you are a Marine Force Reacon guy, or Amry Ranger and you are shooting these great 6.8 bullets and killing every enemy. No problem, right? But wait.... You have run out of ammo. you can not resupply from friendly troops, and no one has 6.8 anywhere. You are screwed.  \n\n6.8 is battering M16's to death too. its way too powerful for the gas operating systems and the recievers.\nIf we had new guns built to stronger tolerances then 6.8 would really be great.

The second set of numbers represents the length of the brass in millimeters. A 7x ("x" reads "by") 57 means that the case, just like an 8x57 is just that, 57mm long. While strange by US standards, try explaining the meaning of 7-08Rem or 7-30Waters to those on the east side of the pond. I also have and love my 7x57. Very mild, but shoots good and flat out a lot further than I can see. My neighbor has a Mauser in 7x64. Wonderful round! Finding ammo is a bit problematic though. He forms his brass from .270Win Seems to work for him.

Bound's hubby here:\n\nA grain is a very precise unit of measurement. a grain is 1/7000th of a pound ... 7000 grains to a pound.\n\nIn rifle and pistol ammunition, the bullet weight is expressed in grains, as is the powder charge. For example, a typical .308 Winchester target round would be a 168 grain Sierra MatchKing loaded on top of 41.5 grains of Accurate Arms 2520 powder.

Berretta M-9 ,  1911A1 45 ACP,  and i just read a article recently that they ordered around 500 Ruger 9mms

.45ACP is indeed the 45-caliber Colt Automatic Pistol - just as .32ACP is .32 caliber, Colt Automatic Pistol.\n\nA point of contention though - hollowpoints are not made to fragment inside a target. In fact, if they do so it's a failure of the bullet. The purpose of teh hollowpoint is to expand upon contact (at speed) with liquid medium, such as body tissue, so that the bullet will not pass completely through the target. Why not pass through the target? Two reasons. First, a bullet passing through a target means that not all of the bullet's kinetic energy was used up on the target - it was wasted. Secondly - and the main reason police (and I) carry hollowpoints - is that they pose less hazard to innocent bystanders if they don't pass through our intended targets.

Any question you can ask in the realm of handgunning will generate a host of opinions -- none of which may be the same.  The 9mm is a fast round but may overpenetrate in the area of self defense but this may happen if you use a + P load in 38 caliber.  I usually carry a 357 revolver (which of course also fires 38's) since I don't have to worry about a safety if I have to use it.  For a long time the 38 was the preferred round by many law enforcement agencies before the 40 and the 45 ACP came into favor.  The drawback for the 38 is it is primarily a revolver round while the 9mm is used mainly in autoloading pistols.  It is also used by the NATO forces.  Many people like the idea of having 10 or more rounds that can cycle through and fire quickly as is the case with the 9mm -- assuming your pistol doesn't jam!  With a 38, you are limited to 5 or 6 rounds from a revolver and your ablity to reload quickly with a speedloader you trust and are proficient in using.  As far as stopping power, both are fine rounds and vary according to what kind you get (higher pressure +P loads, jacketed hollow points, etc.) and where you place the shots.  Both are fine rounds for out on the range.  If either round hits a person, I doubt it will tickle!  Both have been around a long time, since about 1902 and are among the most common cartridges made so finding ammo in either caliber is easy no matter where you go.  I think both are fine rounds, as I have fired both.  The recoil of both is about the same in my opinion.

Bound's hubby here:\n\nThe terms "cartridge" and "round" are interchangeable. Both refer to a complete shell. A cartridge/round's components are: \ncartridge case (brass),\nbullet (the projectile),\npowder (the propellant), and\nprimer (the ignition source).

An M4 is capable of full auto fire and has a fixed carrying handle, an M4A1 is capable of three round burst fire and is equipped with a detatchable carrying handle mounted on an accessory rail, and the M4A1 Sopmod is has the full auto feature and the M4A1 style accessory rail.

best option for that one is to check with a good reloading manual- loads can be so twitchy when you fiddle with them that I have gotten to where I only rely on S.A.A.M.I. member commercial info (at least then you can blame somebody else for screw ups)- I did up some .45 APC with a recommended load (non-manual), and wound up with split cases on 3 of 3 shots- scary!
