Here's one of my little 500 BPE rifles. A Thomas Mortimer single shot. Outside has seen a bit of use, but the interior of the barrel is perfect, it has Henry Rifling in it. I shoot a 350 grain Paper Patch bullet with blackpowder. I shot it last weekend in one of our local Blackpowder matches and had a ball with it. It weighs 6lb 15.25 oz, I'm guessing it would have been right on 7lb when it was ordered.
