I have heard alot of stories about people killing deer with .22's. I think most of the time it is a load of crap made up. I am not saying that it has'nt happened. I am big time against the use of under caliber weapons for big game. I myself came upon a yearling doe wich had darted and jumped into a wooven wire fence and had broke her neck, I figured I would just shoot her with the .22 and put her out. So i preceeded to shoot her point blank in the head in the temple with my .22 long rifle with high velocity ammo. I shot her 3 times in the head and she was still trying to get up, it din't do crap, I than precceded to shoot her twice in the heart before she finally expireded from them last two shots. Don't ever shoot a deer with a .22 it is not enough. After experiencing this myself firsthand I think most of these stories of shooting deer with .22's is a bunch of B.S. and stay away from it.
