PUT ME IN COACH!! I'M READY TO PLAY!!
Hi Froogal
First things first "PLUS ONE for Professor Marvel"
Now. I'll be direct. The "fellow" who told you of the "little trick" of placing a small amount of Smokeless in the case, under the Black Powder, is a LOON!! Bat Shi@#$ crazy. Just because you can do something stupid, and have gotten away with something stupid, doesn't mean you should do something stupid. STUPID can be fatal. I would be want to stay as far away from Mr. Little Trick as possible.
Black Powder fouls. Simple concept. The nature of the beast. There are many suggested remediations. NONE actually stop the fouling. Just some mitigation. With properly set up guns, good quality BP, good bullet choice and a good lube, it is not unheard of to run a full match shooting BP.
Bullet choice not only entails a good alloy for the bullets, but also lube grooves that carry enough lube, lube of the correct type for BP. With some guns, there is NO way to get a 6 stage match. There is NO way to get 6 stages without an amount of fouling. With some guns, chasing a full match without some maintenance is a fools errand indeed. The gun will tell you how badly you're screwed.
The INSURANCE POLICY: Tote a small spray bottle of PAM (equal parts Hydrogen Peroxide, Alcohol and Murphys Oil Soap) and a hand rag. If necessity rings your chimes, squirt some PAM on the rag and wipe down the cylinder face (5 - 6 seconds) then put a squirt on the Cylinder Bushing/Frame join (1 second). If you just can't stand 10 - 12 seconds of piddling between stages, you're in the wrong game. And, there is NO point in trying to shoot modern Replicants of the Schofield with BP.
It's a FUN game. BP is funner then that Heathen Fad Smokeless stuff. Have fun with the game and play it safely!!
Stay Safe out there
