About hangun ammo...sometimes I come across this or that about alternating hollow point ammo (HP/JHP) with FMJ in a magazine (or hollow point with semi-wadcutters etc in a cylinder). Mixing HP with Glaser slugs/Magsafe etc is another. The merits of mixing seems to be, as best as I can tell... 1. Gaining the penetration of FMJ while still having the trauma of JHP. With smaller calibers, a JHP may not go through arms/hands with enough energy left over to hit vital organs, but a follow up FMJ likely would (It's always likely that a direct shot at center torso will be obstructed at the worst moment). 2. Reliability. FMJ usually has less feeding problems. If half the rounds in a magazine are FMJ...less likely to fail to feed. A couple facts... 1. FMJ is less effective than JHP concerning torso hits, but it's likely, in a given caliber, to penetrate greatly more tissue. 2. Alternating ammo will effect accuracy, but not enough to matter inside close quarters. 3. Alternating ammo may effect firing characteristics of a handgun, especially mixing +P with target ball or heavy FMJ with lightweight HP or solid with frangible etc etc. Anyway I find it interesting even if not proven to be any advantage. Any opinions on the tedious idea of loading mixed ammo? Wanna kill these ads? We can help!
