223 caliber in the case of the M16 - travels very quickly to the target. A relatively short, small round - 5.56mm or. Typical rifle rounds generally aim to maximize the first two effects, laceration and crushing and cavitation. In extreme situations, it can even cause damage to nerve tissue, like the spinal cord and brain. This can also cause separations and tears. The cavity pushes outward, compressing the flesh and the energy in the compressed flesh keeps traveling outward until it dissipates. That temporary cavity discussed above? The flesh all around it is obviously compressed as the cavity expands, and that's where the shock wave starts. The cavitation and re-compression is so violent that you can see a small explosion in the first block from the compressing air.įinally, there's the shock wave. There's the laceration and crushing immediately around the bullet, the huge cavity as the gel flies apart, and the shockwave from that expansion as it forces the gel to fly outwards before re-compressing. In the above GIF of ballistics gel taking a. The flesh can tear and cells can burst as the tissue erupts outward and then slams back. That flesh maintains its momentum for a fraction of a second, billowing out from the path of the bullet. As the round travels through the body, it's crushing the flesh and pushing it out of the way very quickly. The first cavity is the permanent one:the open space left from the laceration discussed above. Then, there's the cavitation,which has two parts. First, there's the laceration and crushing from the round's traversalthrough the flesh. See, there are three major effects from a metal round hitting flesh that are likely to cause severe injury or death. An anti-personnel specific weapon usually has smaller rounds that are more likely to tumble when they strike human flesh. That said, it isn't designed solely for anti-personnel use.

M2 military load uses a 720 grain FMJ-BT bullet at a MV of 2810 fps and ME of 12,600 ft. 50 BMG military load uses a 668 grain FMJ-BT bullet at a muzzle velocity (MV) of 2910 fps with muzzle energy (ME) of 12,550 ft.

50 BMG are available from the major ammunition manufacturers, so the cartridge is strictly for reloaders. "BMG" stands for Browning Machine Gun.Īs far as I know, no factory loads for the. 50 BMG is "The Big One." No other shoulder fired big bore caliber shoots as fast, as flat, or hits as hard.
