Do they sell all copper powerbelts? I have been using lead core, copper plated powerbelts. They put about a 2.5" entrance hole and no exit hole. I found pieces of the bullet as far away as in the neck. Too much meat ruined for me. Anyway, is this a problem with all lead cored bullets, as I have shot T/C shockwaves that came with the gun. I got real nice groups with them, but never hunted with anything other than the powerbelts.
