I'm no builder, so I guess it'll have to be an off off-the-rack piece. Also, I'm not fanatical about HC or PC (both meanings), but I don't want an abomination either. Actually, I saw a used NSW .58cal. trade gun at Dixon's on Saturday that fit me perfectly, but I was concerned about how thin the muzzle was. Roger asked what I'll use it for. Roundball only for target shooting mostly and an occasional woods walk. I also thought .62cal was a mite large and a bit more bruising than a smaller caliber/gauge. Keep the advice coming, as I truly appreciate it.
