My Father threw his away and started carrying a M1 Garand after his first fire fight (Bouganville). They shoot great, the problem is what you shoot at doesn’t go down. Arty unit in Korea counted 41 bullet holes in one sapper before he went down. Arty units were issued M1 Carbines, not Garands. Its a pistol round, not a rifle round. Ask yourself a simple question; would I go deer hunting with this rifle? If answer no, then don’t use for people or zombie hunting.
People always get to count the bullet holes AFTER the target goes down. Fact. I guarantee that the guy didn’t stay up for 41 bullet holes, unless everybody in his unit was aiming for his big toe.
It’s NOT a pistol round. Which pistol was invented for this round before the M-1 Carbine was introduced?
And, deer are far more robust than humans. They have a more distinct flight reflex, running with a lung blown out until they bleed out. A human doesn’t have the constitution to do that. And a deer doesn’t fire back, so the concept of suppressive fire and maneuver doesn’t enter into the equation, either.
Since the dawn of the firearm, soldiers have ALWAYS wanted more firepower. I can’t blame their initial desire, but at some point logic has to take over. Everybody wants to make the 1000yd shot, but they rarely see the enemy past 100 yards unless they’re in the desert.
I wouldn't use a 5.56 for deer either.
