My dad bought me one a while back. I didn't know anything about them before that, but thought it shoulderd pretty comfy. If I recall I was getting good accuracy "out of the box" with 777 and a 250gr xtp.
Since then I've massaged the gun a bit. Put a scope up on top, lapped the barrel, fabricated a breech plug to accept a 32 s&w, and a trigger job. The factory trigger was almost ten lbs, its closer to 2 and half now. I also only shoot conicals, it seems to like those and pyrodex p.
Anyways, mine was a gift, not that it matters, shoots good and cleans easy too. I think they are a bit cheaply made, but if you were to do something about the sights and trigger its an awfully fun gun.
