I bought one last year and put a red dot on it. I'm loading 100 grs. Of Pyrodex RS under a Federal Muzzleloading Trophy Copper 50cal. 270 gr. bullet. Used it in the early ML two day season and killed a doe. Didn't see one close enough in the late season. Trigger on mine is great and its so easy to clean! Oh yeah, I used regular shotgun primers.
