Saw this listed as a muzzleloader on an auction site. Description says new Thompson Center barrel on an older action. Seems confusing. The action is a falling block, meant to fire a cartridge. You can see the firing pin in the breechblock. But if you drop the block using the lever, is there then a nipple to cap? Firing pin hits nipple? Seems kinda complicated. I know an Italian company made a rolling block replica that was a muzzleloader. Guess on that one you rolled the breech back, exposing a nipple? In either case, seems like a lot of complication to make an inline rifle. Maybe I am missing something.....
