First off let me say congratulations to Mr. P the younger and to Dad. Well done. How dare anyone belittle this young man in any way. As far as .223 being enough gun for deer IMO its not. So I don't hunt with mine. I've taken deer with 22lr,.243,30/06,.308,.270,.300 win mag and bow. Once with a .410 with #7 1/2 shot on a bet. (very dumb) Never lost one. It was said many times on this post -PICK YOUR SHOT. BTW My son was 8 when he got his first deer. A black tail doe about 100 pounds with a 20 gauge shotgun. That ought to stir 'em up.
