Bad guys and zombies stop being a treat when they drop their gun and decide to play nice or they are incapacitated. The way to incapacitate a threat is either through blood loss or a hit to the CNS (Central Nervous System). This is why shot placement is often brought up as a more important factor than projectile size or type. If you could stick a high-velocity .22lr through someone’s spine and actually sever the cord, you might stop the threat faster than several much larger rounds through soft organs. The hits to the soft organs might even prove fatal but the threat may still be in the fight until the pump stops working.
There are now also projectiles, such as 75-grain TAP, that appear to be more destructive than other 5.56 projectiles such as the M855 ammo the military issues. Since we civilians don’t have to comply with the silly Hague Conventions (yeah, that’s a whole other thread we can debate), we can choose better projectiles for our personal protection needs. Would I rather shoot Mr. Zombie with a .50 BMG to the head instead of a couple 5.56 rounds to the stomach? SURE! But as much fun as it is to shoot LarryG’s ultra cool .50 BMG rifle it isn’t a practical house clearing weapon due to size, weight and ability for fast follow-up shots.
All these weapons have their place. In some situations I’d be grabbing the FAL and a few dozen magazines. In other situations you might find me behind the belt-fed in a sandbag bunker in the front yard sipping on a beer. And when the alarm goes off at night I’m grabbing my suppressed SBR loaded with 75-grain TAP and won’t feel under gunned in the least.
Debating calibers is a silly, futile exercise without considering various situations and the best solution(s) for that situation.
You guys all have a happy, blessed day and whatever you choose for self defense just remember to practice often and train hard.
Debating calibers is not futile. Ask the soldiers in the Phillipines. .38 would not stop the threat. .45LC would stop the threat. You can talk about shot placement all you want but there have been too many real life experiences where shooting paper does not equate to be shot at in real life with a BG coming at you.
