Yeah, if I'm going to make a gun Ka-Boom, it won't be unexpected, or an accident.
Like, if I bought that CVA Buckhorn 209 Magnum muzzle-loading rifle for $50 and decided to see how it worked with Unique smokeless powder, starting with 10 grains and working up until I get to a good hunting load OR the rifle blows, whichever happens first.
(But I'd have the gun buckled-down to a lead sled, and pulling the trigger with a string from behind a tree...)
