Re: [Emc-users] Flash hole drill sizes for BP with 209 ignition?
On Thursday, May 24, 2012 09:56:21 AM dave did opine: I'd feel better is the cover/latch had a gas vent to move gas away from the shooter if something ruptures. 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. I have a #11 nipple for this one too, but the CCI #11 Magnum hasn't the fire to do anything but a noticeable hangfire at best. I tried it twice, the first time there was a 3/4 second hangfire, the 2nd I wound up unscrewing the breech and putting about 10Gr of 777 in, and rather forcibly screwing the breech back in. That fired nicely, and while it was a bit of a PIMA to load the 777 first, then the BH209, the resultant accuracy was much improved. Pacing the barrel heating, I fired nearly a full card of bullets, winding up with a 10 shot group of just over 2 at 50 yards that day. BH209 being a smokeless but with added smoke, seems to heat the barrel faster than the other black subs, so 6 shots were enough to warm it nicely, potentially damaging the sabot by melting. A couple of years ago I did a golf ball mortar using plain old fashioned fuse; was good for about 150 yards. :-) That's better than my drives 98% of the time. :) I have been out on the coarse a few dozen times, but can't say as I can 'play' the game.

Some of the children I play with have a cannon. Ricky's I did the iron work on a few years back. It is a 2 1/4 bore cannon. Ray bought the same cannon barrel that I did but has not finished his yet. George has a 1 1/2 bore navel cannon but it is not finished either... and he has been working on it for years. In addition to the cannons Ray and George has a Coehorn Mortar that is finished and we shoot them regularly. You can see Ray's mortar in the video.

I have a #11 nipple for this one too, but the CCI #11 Magnum hasn't the fire to do anything but a noticeable hangfire at best. I tried it twice, the first time there was a 3/4 second hangfire, the 2nd I wound up unscrewing the breech and putting about 10Gr of 777 in, and rather forcibly screwing the breech back in. That fired nicely, and while it was a bit of a PIMA to load the 777 first, then the BH209, the resultant accuracy was much improved. Pacing the barrel heating, I fired nearly a full card of bullets, winding up with a 10 shot group of just over 2 at 50 yards that day. BH209 being a smokeless but with added smoke, seems to heat the barrel faster than the other black subs, so 6 shots were enough to warm it nicely, potentially damaging the sabot by melting. Ugh! Hang fires are scary. Most unsettling! Those aren't bad groups even at 50 yds. I've got .22's that won't do better even off a machine rest; about 2.5 x 2.5 inches for 30 shots. I'm fairly convinced that 5 gr or so of FFFg down the barrel followed by the correct charge of your favorite powder is the way to go. Most of the BP substitutes seem to need an extra push. Even the military uses BP as an initiator for large bore stuff. Since sulfur is added to BP to aid in ignition and really doesn't do much else I've considered using carbon disulfide to extract the sulfur from BP and then using a small amount of real BP as an initiator. I think it would burn cleaner. Of course, the easy way to do this is to add energy by using 10% smokeless to make things burn hotter.

The latch sounds like a good idea (I hate thinking about anything, striker, gas, or otherwise, kicking toward your face) but I have no idea how hard it will be to implement. Now BP cannons I could see myself getting involved with...kind of an East Coast mythbuster...making smoke and noise in equal quantities and bouncing cannonballs through peoples' backdoors. Heck, they even get paid to do it. Regards, Kent I'd feel better is the cover/latch had a gas vent to move gas away from the shooter if something ruptures. 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.
