Yeah BPS, mine is 16xxx. Doesn't really matter to me, its pristine, has double triggers and a nice TC peep.
Now I just gotta find some time and work up a load for it. I've never shot it yet, and in fact...I've never shot a prb ever out of any rifle. All the sidelocks I had I only shot conicals out of.
Suggestions? I plan to get some real BP to try in this gun, but I may start out with Pyrodex RS as I have plenty of that.
