You need more range time man. Also maybe a single shot rifle or muzzleloader... Then you will be more patient with your shots if you only have one...

I don't think I've missed 8 deer in my life let alone one season.

Have some respect for the animal that YOU pulled the trigger on... big or small you killed it. Be happy with it. It ain't about antlers anyway. That's just how it is on the TV...

BTW... I too have shot a spike I thought was a doe. one antler was 2 5/8 in long the other 3 1/8... anything over 3 is a buck, so I tagged it as such happily. Still have his lil rack in my office...
