I've been wanting to post about blackpowder and Perentie's thread seemed like a good reason to, but I don't want to clog his question with my rubbish so I started another thread.
I've been shooting a muzzleloader occasionally for a few years, purely for the giggles. Due to our crazy handgun laws I'm able to start shooting Cowboy with a pair of revolvers, as long as they're not cartridge revolvers. After six months I can buy cartridge revolvers so whether I stay shooting black remains to be seen, but it is great fun. Last month I finally got a pair of 1858 New Model Army .44 revolvers, and have started testing blackpowder in .38 Special in the lever-action rifles. I need to start loading blackpowder .30-30 as well. As with Perentie, I'm also interested in how long I can run them before the fouling becomes too awful. Ian McCollum has been doing a series "Having Fun With Blackpowder" using old breechloading milsurps and I think they're starting to see issues after a few dozen rounds. With my Hawken Rifle I find it gets very difficult to push the ninth or tenth ball down the bore, but I think a lot of fouling can be reduced by using the right lubes in the right amounts. Karl Kasarda found with the Schofield revolver that adding a couple grains of smokeless under or above the black charge can help burn out a lot of the crud, but I haven't tested that myself yet. I'm not sure if it was Dustin or Jake but one of the guys from Everything Blackpowder or Guns of the West got surprising results putting the duplex load on top of the black charge, cleaner burning and higher velocities.
A local Cowboy match is generally going to be four or five stages, each firing five rounds in each revolver, ten in the rifle, and two or four rounds in the coachgun. So, for myself, about 25rds in the revolvers, 50rds in the rifle and 20rds of 12ga. When Rose shoots with me we could double that, or she could shoot smokeless .38's in the rifle and smokeless 12ga. loads. If the club's Vaqueros are available she could even shoot those instead of the .44's. I don't expect to start seeing issues with fouling after that few rounds, but if I stay back and practice after the match then it will add up and will likely become a problem. I'm hoping to put a lot of rounds through the revolvers and the .38 lever-action on Sunday as I want to determine how many I can fire before I start having issues. I've put a few dozen black .38's through the Uberti 1866 without any issues at all, but I think the old pistol-caliber levers have fairly wide tolerances.
I want to play more with grease as I think that's the key. Powder with a ball on top, with no grease I think has the biggest fouling issues. A lubed felt wad under the ball can help lube the bore, but they're an expensive way to shoot if you're buying them. I'm using a lubed patch in the muzzleloader and a lubed wad under the ball/bullet in the revolvers and the .38 cartridges, but when I use up the 1000 I bought I don't plan to buy more wads. I bought 500gm of lard the other day as I want to experiment with grease cookies under the bullet in the .38's, and grease on top of the ball in the revolvers. Grease cookies can be a little tricky to set up as you want just the slightest compression but not enough to squeeze the grease into the powder. I haven't decided what to use for a card between the powder and the grease though. Something impermeable ideally so the grease doesn't soak through into the powder, a .375" plug of 5mm foam rubber might be good, the more you compress it the tighter it should seal against the sides of the case.
I haven't experimented enough with charges to determine whether heavier or lighter charges create more or less fouling. I used to shoot 70gn in the .45 Hawken but I've dropped back to 40gn last year for a more fun experience. I haven't yet done any accuracy testing with blackpowder in anything as I only use them at very close ranges. I will have to do this with the .30-30 if I want to have any chance of hitting that 500m bison silhouette though.
For the revolvers I bought a hand vice that seats all six balls together, which greatly speeds up reloading the revolvers and I've ordered two different paper cartridge kits. I think paper cartridges will really speed up the reload. Instead of dropping the six charges in from vials, then pushing in six wads, and dropping six balls on top, then seating them all together, I'll just drop in the six cartridges and seat them as one. It might take me longer to cap the six nipples than to load the cylinder. I'm leaning toward pre-loading syringes of grease that I can just squirt into the chambers without even having to look at them. I haven't decided on what to use for grease yet. I don't want to use a petroleum product that needs solvents to break down when it gets into your clothing, so something vegetable- or animal-based sounds like the way to go.
VAPA does not allow wads under the ball/bullet, and requires grease on top to fill the chambers. But only one person I've chatted with so far has complied with that, most run a wad and only one person greases on top of the ball. One guy did have a chainfire years ago and has never fired his revolver since then.
My first loads in the .38 Special were 17gn of FFFg, a lubed wad, with a 125gn cast bullet seated at 1.475". This load made 870fps in the Uberti 1866 20". So this week I loaded 50rds of 15gn, lubed wad, 2gn polenta to take up the space, and the same bullet seated to the same length. These make 1044fps, 175fps more than the 17gn load, and 30fps more than 3.3gn of AS50N measured in the same session. I'm assuming I had more compression on these due to the polenta. These loads had ES of 60fps and 57fps and SD's of 20fps and 18fps so they're fairly consistent. I want to try 12gn next, without the wad, just polenta filler, and perhaps a 3mm thick cookie of grease on top of the polenta. I may paint the driving bands of the bullet with Liquid Alox as well, I'll decide if I can be bothered at the time. The blackpowder is nearly double the price of smokeless and I'm using five times as much of it so this is expensive shooting. The wads are more expensive than the bullets so they have to go.
Something else I'm curious about with the .38's in the rifle. If I shoot a Cowboy stage of 10rds of black, then Rose shoots a stage with 10rds of smokeless, and we alternate through the match will that clear out any of the fouling?
Permit came through on my Rossi Coachgun yesterday (despite my licence being expired still) so my next trick is loading 12 gauge blackpowder loads. Do I buy more Magtech brass or just use plastic hulls?
