RE: Muzzleloader scope mounts??
See-thru mounts are a snare and a delusion. They put the scope WAY TOO HIGH up in the air, so you have to crane your neck and get your chin up off the comb to use the scope. Bad news!! If you have a scope on your gun, it is the primary, not an auxiliary, sight. I have a detachable mount, but rarely detach it, I just scrub the fouling off the bottom of the scope with a cleaning patch.
Keep yore powder dry!!
