I wouldn't do it. It makes a mess dirt wise. And is corrosive. You would have to take down the pistol and thoroughly clean it. If you want to try a black powder that is cleaner is suggest. Black horn 209. It's supposed to be cleaner. I have not used it myself.
Howdy
I love these statements that claim you have to completely disassemble a revolver after shooting it with cartridges loaded with Black Powder.
I have been loading real Black Powder into cartridges and shooting them in revolvers for over 20 years. 45 Colt, 45 Schofield, 44-40, 44 Russian, and 38-40. 45-70 too, but I don't shoot that in a revolver, only in my antique Trapdoor rifle.
I NEVER take a revolver completely apart after shooting it with Black Powder. Any revolver that I plan to shoot with Black Powder, I take apart completely, degrease everything, then I relubricate with Ballistol.
As has been stated, Black Powder is not as corrosive as most people believe. Yes, it is corrosive, but nowhere near as bad as most people believe. Yes, it was corrosive primers, coupled with BP fouling that caused most of the trouble. We don't use corrosive primers any more, so real BP is far less corrosive than many shooters believe.
Yes, cleaning up after shooting BP is messy, no question about that. Far more messy than cleaning up after Smokeless. On the other hand, my favorite BP cleaning solution is water based as opposed to the nasty chemicals in most Smokeless cleaning solutions.
Yes Black Powder fouling is very dry. Yes, it is hygroscopic and will absorb moisture from the air. When BP fouling sits against steel for an extended length of time, it the moisture held against the steel will cause corrosion.
But here is a little secret I discovered a long time ago: Soak BP fouling with oil, and it cannot absorb any moisture from the air. Think of it as a sponge that is already saturated with water. It cannot absorb any more water. BP fouling soaked with oil cannot absorb any water in the form of water vapor from the air. So there is no water to be held against the steel. When I clean a cartridge rifle or revolver that has been fired with Black Power cartridges, I swab everything out real well with my favorite water based BP solvent. When I'm done I take a dry patch and soak it with Ballistol. I run the patch through the chambers and bore, to soak them in oil. Then I follow up with a dry patch to mop up the excess. This leaves a thin coating of oil so any minor traces of BP fouling left against the steel will be harmless.
This is particularly useful when shooting antique revolvers and rifles with pitted old bores. It is impossible to clean every molecule of fouling out of the pits. I don't bother. Instead, I give everything a nice coating of Ballistol which makes any fouling left in the pits harmless.
Yes, cleaning up after shooting BP is messy. But it is quick and easy. It requires less elbow grease than cleaning up after Smokeless. Cleaning a cartridge revolver after shooting it with BP cartridges is easier than cleaning a C&B revolver because the chambers are bored through the cylinder. No nooks and crannies as there are in a C&B cylinder. No nipples to deal with. Just run the patches straight through the chambers.
Did I mention I have been doing this for 20 years?
Oh, to the OP, no point trying to load 30-30 with Black Powder. 30-30 has always been a Smokeless powder cartridge since it first appeared around 1894 for the Winchester Model 1894.
