^^^ I never said that .30-30 is marginal for white-tail deer. It's about equal to .308 Win which I sited as just right for that animal.
It is NOT the "correct" round for taking down "big" game. Yes, it can. But it isn't morally right.
Let's say that someone shoots ME and I'll have no way to defend myself nor have any hope of surviving in the end. I'd want that person to use a 12ga to my head... not a .22LR to my gut.
I'm just sayin'...
ETA: Before anyone argues about "shot placement" (gut vs. head)... yeah, with no hope of surviving I'd FAR rather have a 12ga shot to the gut than a .22LR shot to the gut... or a 12ga shot to the head than a .22LR shot to the head.
