Search the internet for two of my posts:
"Proper Use of a Cap and Ball Revolver"
and
"So You Want a Cap and Ball Revolver?'
Both by me, Gatofeo.
I've been shooting cap and ball revolvers since about 1970. These two posts contain much of what I have learned over the decades. I've been posting them on the internet, in various message boards, since about 1999. Look for one posted within the past 10 years for more modern info.
But for the gist:
.454 balls
Black powder is more accurate than black powder replica powders, but real black powder can be difficult to find. I'd suggest you use Pyrodex P.
Remington percussion caps are preferred, but CCI will work fine.
No way of knowing whether your revolver's nipples will take No. 10 or 11 caps. Buy a tin of both, for starters.
Hard wool felt wads between powder and ball will keep the bore cleaner longer.
Lubricate the hard felt wad with melted SPG, Lyman Black Powder Gold or the homemade lubricant named after me: Gatofeo No. 1 Lubricant.
See my posts for directions on making and using Gatofeo No. 1 Lubricant for wads, bullets and patches.
Wear eye and ear protection.
Never let anyone stand to the side while the revolver is being fired. These guns release a lot of ejecta that can cause injury.
During firing, keep and powder, powder flasks and caps well behind you, away from sparks.
Don't smoke or use alcohol while using this revolver, or any other firearm for that matter.
Clean the revolver right after use. Black powder and substitute powders can attract moisture and quickly promote rusting.
Never underestimate the lethality of cap and ball revolvers. They have killed millions and still may.
Be wary of Slackjaws who urge you to load to maximum or beyond the recommendations. They are morons.
Be wary of Hodgdon 777 black powder substitute powder. Visit the Hodgdon powder website to learn its proper use.
If you have a brass-framed revolver, don't load it to maximum. Brass-frames are damaged by the cylinder slamming back under high pressure.Keep loads moderate.
Have fun with that revolver. Look for my posts under the name "Gatofeo" for detailed information.
Enjoy! Be Safe!
