Funny thing. When you hit a crow with a 45-110 and a 535 grain paper patched bullet, it doesn't blow them up. It punches a hole through them, and maybe knocks out a couple of feathers. Same thing with a 40-70 Sharps Straight or a 40-65. Kills them graveyard dead if you hit them at the butt of the wings, but hit them a little far back, and they will get up and fly off--and then fall out of the air.
