I too live in PA. I just bought a Traditions PA Pellet and have not shot it yet. I bought at d&r sports online. Got the camo/nickel for $230. It has the new improved super lock. Check out my earlier posts for more info.
From advice I've got use loose powder for best results and dont start with 150 grains. Start at about 75 and work up till good grouping. A real nice gun for the money.
