Re: Traditions keystone hunter
My Deerstalker has the 1/48 twist and it shoots well with PRB. As to the rest of the gun, I have no experience with that model so I can't help you too much there. A 1/48 is a good middle of the road barrel for both PRB and bullet-style projectiles as far as I understand it. Good luck with it whatever you decide to do!
A bad day hunting rabbits beats a good day of anything else!
