I hope he doesn't buy anything with a "bolt-action" because a bolt on a muzzleloader is about as useful as a screen door on a submarine.
Yeah you need those 2 contact surfaces to bear evenly to keep that "cartridge" aligned properly and all
. Not to mention I love to clean out hard to reach lug recesses and still have substandard accuracy. Don't get any better
Think the same people that buy into bolt action muzzleloading rifles probably buy buttout tools for field dressing.
