[QUOTE="Turpentine21, post: 2950384, member: 124909"] Nathan's studies for me are interesting from a hunting standpoint but also interesting if you look at what has happened to our 5.56 military cartridge and rifles over the years. First they used a high velocity 55 grain bullet from a 20" 12 twist barrel IIRC. The 12" twist only marginally stabilized the bullet which produced some initial yaw in the projectile. Combine that with the higher velocity and you got a very high likelihood that the bullet would tumble on impact and create larger wound channels. Then we decided that the combination created inhumane wounds. Introduce the m855 and the 14" barrel of the M4 today along with a much faster twist rate. It barely makes the tumbling threshold at muzzle velocity and is much more likely to pencil through therefore creating a far less inhumane wound and in my opinion decreasing the rounds knockdown or killing power significantly. I don't know. I was bored so I figured I would share that. [/QUOTE]
