Don't forget black powder in cartridges. A lot of CAS competitors shoot BPC guns. For revolvers the Colt SAA and it's many reproductions kind of rule but there's good representation for the open top cartridge conversions, usually paired with an 1860 Henry or 1866 Golden Boy rifle. Colt style strap pistols are generally backed up with a 1873 Winchester. All shooting black powder cartridges.
Howdy
That's right. Most of the guys I know in CAS who shoot Black Powder put it in our cartridges. A few use Cap & Ball, but most use cartridges. I got my first Black Powder Cap & Ball revolver in 1968, but I've only actually brought a pair of Pietta 1860 Armies to a match once. Too many cap failures and cap jams, plus to be honest it is so much simpler to throw cartridges in the cylinder than it is to fuss with loose powder and ball that I have not taken them to another match since. Yes, there is a modification that can be done to prevent caps from falling down inside the works, but it is so much easier to just use cartridges that I have not bothered with that mod. The only real advantage to C&B is if you don't have any ammo loaded up you can just bring powder, caps, and ball and load when you're there. But we have to use cartridges in our rifles and shotguns anyway, so it is so much simpler for me to shoot cartridges in all three.
My usual Main Match pistols is this pair of 2nd Gen Colts chambered for 45 Colt. They have had a little bit of work done to them to slick them up, but not a whole lot.
They make plenty of smoke.
A few times a year I will take this pair of antique Smith and Wesson New Model Number Threes. The one on the left has not had any work done to it, other than wear and tear it is just the same as when it left the factory in 1896. The nickel plated one was factory refinished in 1965, bringing it back to the appearance it had when it left the factory in 1882, but nothing has been done to slick it up. This pair is chambered for 44 Russian, the most common chambering for this model.
Once a year or so I will take along my Merwin Hulbert Pocket Army. No modification has been done to it, it is just like it left the factory around 1880 or so, except for about 140 years of wear and tear.
The Merwin is chambered for 44-40, so it puts out a good deal of smoke.
My Main Match rifle is my 1860 Iron Frame Henry made by Uberti. Also chambered for 44-40, it has had a couple of minor modifications to make it a little bit friendlier to shoot than bone stock.
It puts out a pretty fair cloud of smoke.
My main match shotgun is this lovely little old Stevens 12 gauge hammer double. Somebody cut down the barrels to 24" before I owned it, so it is open choked now. Other than that it is just as it left the factory sometime around 1908.
It too is no slouch in the smoke department.
