I've been working with it for nearly 5 years now. While I don't claim to be the best shot in the world, I know I'm better than the performance I have gotten out of this gun.
I have tried Triple 7, Pyrodex and BH209 in charges ranging from 80 up to 120. I have shot Deep Curls, Shockwaves, Partitions, Barnes, Expanders and Spitfire TEZ's and Hornady XTP's all with various sabots. I swabbed between shots and left it dirty. I have shot it with standard sights and a peep.
Finally I threw scope on it last year in hopes that I was the problem. Still no luck...2" at 50 yards. That was when I decided maybe it was time to try something different.
