I'm sure it depends on Make and Model as well as design but i wonder waht kinda of charge it would take to blow a muzzleloader like that? My CVA will handle 150gr of Pyrodex Pellets(3 pellets) which is considered a magnum muzzleloader charge. That is the biggest load my gun will handle and the biggest i've heard of on any muzzleloader. To me 150gr packs a pretty good punch. What point would be dangerous? Just curious. I would never push the limits of any gun.
