Based on my assumption that there are less critics of a common and long existing .22 caliber semi-automatic rifle, like the one I gave my grandson, than of a .223 caliber semi-automatic rifle that has been labeled an “assault” rifle, I’ve been doing a lot of research on where the truth lies and so far it remains elusive.
Yesterday my son dug through his junk box and came up with a couple of different sample rounds, a 9mm and a .223. I searched and found a .22 hollow point. As you can see in the photo I took the 9mm projectile is quite larger than the other two but the case of the .223 is much larger. The diameter of the .22 and the .223 are almost identical with the .223 projectile being somewhat longer and more aero-dynamically shaped. The cartridge case of the .22 is miniscule compared to the two other rounds.
So, what’s all this mean? It means my grandson’s .22 semi-automatic shoots a bullet almost identical to the military .223 used in an AR-15. The target is getting hit by about the same amount of metal. The 9mm bullet, being larger, will cut a larger hole in the target. In addition to the bullet size is the amount of gunpowder in the cartridge case, the more powder the faster and further the bullet will travel. And when it arrives at the target less energy will have been spent and the potential for damage increases. If the target is an animal or human the bullet may begin to tumble as it enters the body which could multiply the damages. Distance would also be a factor. On the assumption that the 9mm would be shot from a pistol distance would have a major influence on bullet’s potential. Being fired from a rifle the bullet could travel further before losing it’s ability to be effective. In this comparison the .223 reigns supreme because of its speed or velocity.
While there is no end to the science behind ballistics and to the debate over which is the best ammo round. The one truth I understand is that every bullet has the potential to kill. Oh, and that includes a BB, “it will take your eye out!”
