I have wanted to shoot 1875 Remingtons using BP in SASS events, but have only heard that using BP the cylinders foul so bad you cannot get off your five shots! Tell me it ain't so!!
It ain't so! Sort of....
I shoot 1875 Remington replicas in CAS, and have done so for several years now. Mine are all chambered in 44-40, and I shoot nothing but black powder. So it CAN be done. That's the good news. Everything that follows deals with my experience with the 44-40 versions. All were made by Uberti, though the importers varied (Navy Arms, Uberti USA, EMF, American Arms, etc.).
The bad news is that some work well with black powder, and some don't. As near as I can tell, the older ones (1970s) work great with black powder, while newer ones tend not to. The difference is in the length of the cylinders.
Keep in mind that I've owned seven of these over the years. The two that worked well with black powder are the two that I still own. When compared to the other five, the only difference I can find is that their cylinders are a little shorter. The frame window is the same size, and the barrel/cylinders gaps are all about the same, too. That means that more of the barrel protrudes into the window on the short-cylinder guns than on the long-cylinder guns. The shorter cylinders also mean that I have to be careful when loading not to exceed 1.592 OAL, because anything longer results in the bullet protruding from the front of the cylinder, where it can hang up on the back of the barrel and cause a jam.
My theory is that the shorter cylinders result in better black powder performance because it results in the barrel/cylinder gap being offset from the point where the front of the cylinder bears against the frame. This results in less fouling getting blasted into that area.
With the older, short-cylinder guns, I can pretty much go an entire match (6 stages) without any noticeable binding and without having to clean or regrease the cylinder pin. The good news is that while the long cylinder guns tend to bind up and need cleaning mid-match, I can usually go two stages without cleaning, if need be. They'll certainly get through 5 shots without trouble, and then it's a simple matter of spraying some Ballistol around the front of the cylinder and periodically relubing the cylinder pin to keep things going. So while some maintenance may be required, you can make them work.
Also, your loads will make a difference. I highly recommend the "Big Lube" bullets, such as the MAV 44, Snakebite .38, DD .45, etc. They carry a lot more lube than commercial bullets, and the lube is what helps keep the fouling soft.
