ThanksAs noted, you may find reduced velocities compared to 3f (the coarser the granulation of powder, the less "energetic" it is when using the same volume), but there's nothing unsafe about doing so or anything that would prevent it from working, if those are your concerns. Load the same way as with 3f and shoot away.
Thanks for the info.Can use FFg. For "same load" velocity as FFFg reduce the FFg powder charge by 10 to 15%
Same as the FFFg powder charge will give somewhat higher velocity, at lower pressure.

I admit to being a bit dyslexic at times (ongoing issues following a couple of bouts of Lyme disease), but I think you have this backwards. A 10-15% lower charge of FFFg powder will give you the same velocity as the higher FFg charge, but you will see slightly higher pressure with the FFFg. So, for instance, 100 grains of FFg will have roughly the same velocity as 85 grains of FFFg and the FFg charge will have slightly lower pressures. That's not to say that one is necessarily better than the other, you need to decide what your rifle(s) likes (or what you happen to have on hand).
I don't want to hijack the thread, but have any of you fellows tried any of the "Reenactor" type powders in revolvers for live fire? I have a couple cans of the GOEX brand, but haven't gotten around to trying it yet. I was wondering if anyone else might have given it a go.
Much obliged,

OK, ThanksOver the weekend I tried both FFg (Graf) and FFFg (Du Pont) in a pair of Pietta Marshal five and a half inch barrel revolvers.
15 grains of powder ,a lubed felt wad, .451 ball with the ball just seated on the wad, no compression.
Of course both loads shot just fine, my perception was the recoil of the FFg load was slightly less and perhaps a bit more muzzle flash otherwise it shot just fine.
With the charge increased to 20 grains the FFg recoil was less, the muzzle flash greater than the FFFg. that recoil was very close to unpleasant.
So either one worked nicely for me
YMMV
Respectfully,
Bunk
P.S. I found several cans of some 1970 FFFg Du Pont and am using it up.
Can I use 2ff goex powder in my 1860 Army revolver? 44cal. Would it be the same charge as 3f?
