Have Any Of You Used 4F Black Powder?
I have heard that 4F was for priming flintlocks only, have any of you used it for Cap and Ball revolvers? If so, did it increase velocity? Did it blow up your gun?
I’ve used 3F in 50 caliber muzzle stuffers, and it does increase velocity, recoil, and fouling. 50 caliber and up usually recommended using 2F. If you have used 4F, did you reduce the charge?
The reason I’m asking, is because with the shortages these days, I could only get 2 lbs of each granulation, so I ordered 3F and 4F, so I have a couple of pounds of 4F that I may not use (for priming) in my lifetime.
It would be nice if a Ruger Old Army (or any other cap and ball revolver)could reach Triple 7 velocities safely, using 4F. Has anyone seen or done any testing of this?
4F
ONLY IN .31s AND .22s (NAA)
Thank You JT
I should probably get a .31, how was velocity and accuracy?
.31 FFFFg

I'd have no qualms about trying 4F in the Ruger Old Army. I used mine, years ago, with, uh...hmmm... unauthorized propellant to much higher pressures than you'd ever get with 4f. Don't think I'd try the same in a Colt open top type, but I'm older and wiser now than back then. Anyway, in the Ruger Old Army I've shot everything from 3F to Cartridge Grade (or whatever they called it - a pebbly looking powder) by Pyrodex (it was all I could get at the time). Then there were the excursions into "unauthorized propellant territory" that proved to me that the Ruger Old Army is basically indestructible with BLACK POWDER and equivalents.
As with any other powder, start low and work your way up to reach the accuracy/power you're looking for. Again - I speak only for the Ruger revolver, not the Italian imports and such as I've little experience with them, and none in anything other than 3f.
