Some muzzleloaders drill a small vent hole coaxial with the drum; apparently it helps ignition but I don't know why. There was a story in "Muzzle Blasts" about a muzzleloader the owner called "old butt burner". It really spewed a flame to the right when it fired. The shooter to the right was bending over with his rear too close to the vent and he did a dive over his bench when it went off. The cleanest solution I've seen was a .25 pistol cartridge (CF) used to ignite the charge. About at the end of the active use of muzzleloading shotguns some were ignited by .22 rimfire with powder but, of course, no lead. However, mz shotguns operate at about 8 Ksi opposed to rifle that may go as high as 25 Ksi with 18 Ksi being more normal. .22 rimfire are at about 11 Ksi. Most of the guys I know are using CCI Magnum #11 caps and getting good ignition. A couple of years ago I did a golf ball mortar using plain old fashioned fuse; was good for about 150 yards. :-) 'Nuf rambling for this time of the night.
