I have a Brown Bess from Pedersoli and it's a very good gun.
I personally would use real black powder. The ignition temp of black is lower than the "fake" powders, and all things being equal that can mean greater relibility, or 100% reliability, period. If you can find Swiss black powder, it is almost as clean burning as the substitutes, but ignites just like real BP, because....it is!
Pellets are for Bat Guns, or modern rifles that load from the muzzle and you probably would not get good results from them. Again just use real BP, Goex is good powder.
What size caps to use depends on what size nipple you have, which is most likely a #11. All my percussion rifles use musket caps, being rifled muskets, (!!!) so I'll leave the cap discussion for more knowledgeable others. I prefer RWS caps on my revolvers...your results may vary!! I did have a #11 cap on one of my muskets for a while, and it didn't really seem to matter what kind of cap I used.
:results:
Here is how I get 100% reliability from my cap-guns. I don't clean them with water, but everyone else here does, so you will just have to make that decision according to what makes the most sense to you. My personal, gut-instinct, unfounded unscientific belief is that some rusting of the barrel will occur between the rubber-ducky wash and getting oil on the bore, and that some amount of water will seep into the breechplug threads, and either eventually rot the theads, or seep back out and contaminate the main charge...making people think that the main charge has somehow abosorbed moisture from the air... NO OFFENSE anyone, just my personal crazy thoughts!
:youcrazy:
Before I load a rifle for hunting, I run dry patches down the barrel and into the breech, and try to get/dry every spec of oil out. I remove the nipple, make sure it is dry, poke the pick through it, and a pipe-cleaner into the larger nipple-part. I get into the flash channel with either pipe cleaners, or a tiny screw driver covered with a patch. Make sure everything is dry dry dry and no longer oily.
:nono:
I DO NOT snap a cap before loading for a hunt, although everyone else will tell you to do so. Again, you decide, or at least experiment. I personally believe, and could be wrong, that the fouling and crud from the cap will cause more miss-fires than any remaining film or trace of oil will, if you have done a good job hand-drying the nipple, flash channel and breech. In fact I don't think a trace of oil will effect ignition, as long as it does not migrate up and into the cap...which a trace amount will not do.
At the shooting range, go ahead and snap a cap and skip the hand-drying process.
Again I have a Pedersoli, (but it's a flinter) and am 100% satisfied with it. Again-again, I think you will get better results with real black powder. At least learn/start with it, get 100% reliability, and THEN you can experiment with the BP substitutes. But don't start out with them, as then if you do get miss-fires, you won't be sure if it's the powder, or your cleaning and loading techniques. In other words take that variable out of the equasion right off the bat.
Good luck and have fun. What caliber is this smoke-belcher?
