*edit* the M16 isn't harder to use than the ak-47. 50 caliber rounds can kill someone by shooting their hand/other extremity due to hydrostatic shock and the bodys water content. This is why "green tip" ammo, which is a AP style round is good at piercing body armor and anything behind it but lacks stopping power, many examples of this can be found in the mogadishu incident from the Delta unit there and the rangers when the Greentip ammo would penetrate straight threw a enemy instead of tumbling. 22 round which will fragment on impact and tumble threw the body. The 5.56mm round is designed to tumble threw soft tissue and cause massive trauma damage to many organs(this can be acomplished with a. Hydrostatic shock isn't really that effective. The M-16 is harder to use than the Kalashnikov, but more effective, except that the bigger, slower rounds in the AK-47 have more stopping power (Due to more momentum). M-16 bullets have less range than an AK-47, and they move faster. That's called hydrostatic shock, and it happens because the little bullet goes so fast that it makes a shock wave through the material. The soldier shot the drum with the little bullet, and the bullet moved so fast that the drum *exploded*.

He then asked the most skeptical neophyte soldier to come up and shoot a drum with the M-16. Both the magnum rifles shot the bullet straight through the drum, making neat holes front and back, with little streams of water pouring out. The demonstrator set up several 55-gallon (about 209-litres) drums full of water. Of course there were some people who didn't believe that this little bullet could do a lot of damage, so they had a demonstration.

223 type bullet, a very small bullet with a whole lot of powder.

Air Force durring the cold war, and in Basic Training they learned the M-16 rifle like all U.S. Wouldn't have much stopping power but if you could get it going fast enough it would work very well. Stopping power comes from how big the projectile is.
