Tripe 7 ok in a brasser?

I want to use Triple 7 FFg powder in my new (replica) 1851 Colt Navy revolver because that's what I use in 12 gauge blackpowder shotshells, and I have plenty of it on hand.

I loaded a couple of cylinders with FFFg I got from a friend the first time I shot this revolver. (Actually, I shmoozed it from him. I bought the beer.) Now I'm going to have to buy some FFFg or a lot more beer, or use the FFg Triple 7 I've already got.

Anything wrong with using FFg Triple 7 in a replica brasser Colt Navy? . Triple 7 is about 15% more powerful than real black powder. If there is no reason not to use Triple 7 in my gun, what would you suggest as a "moderate" load that won't put too much strain on my brass frame?

Any help will be appreciated.
 
What caliber is it?
It's generally recommended to not load more than 25 grains of black powder in a .44 brasser, so the equivalent loads of 777 are below. It doesn't really matter if the 777 is 2F or 3F, either can be used interchangeably with only 1 grain or so of difference. Some folks recommend using filler or a wad with the small loads in a .44 to insure that the ball is seated on the powder and to take up some of the extra space in the chamber.

The equivalent load for 20 grains of BP would be 17 grains of 777 by volume.
The equivalent load for 22 grains of BP would be 18.7 grains of 777 by volume.
The equivalent load for 25 grains of BP would be ~21 grains of 777 by volume.

Triple 7 is excellent nice and clean I use it in my BP pistols and what is real good it doesn't gum up the cylinder like BP. I also use it in my BP shells for pistol and rifle.

Sorry to have forgotten to mention that it's .36 cal., arcticap. I appreciate the information you posted.

Nice to know that you're already doing this with no problem, Maxem0815. My friend was telling me I had to use FFFg powder. Traded me some for a couple of Spaten premium beers and a double corona cigar.
 
Honestly DG45 ... I'll say no, I wouldn't recommend Triple Se7en in a Brass Framed revolver ...use BP or Pyrodex ... I broke a steel framed 1860 Pietta with 777 ffg 28gr in three shots, never used another grain of it ...
That's my recomendation only thru my experiance with it.
Whenever that question comes up I answer it.
 
I've got a couple of brass framed pistols... an 1860 and an 1851.

I've been shooting 777 in them from the start... I have a cache of goex, but I'm hoarding it... the real thing lasts virtually forever if you store it right so it's my third line of shtf defense.

Anyways, my experience has been that while you've absolutely got to try a hot load or two... just for comparison... they aren't really more fun to shoot, just louder.

Therefore I use a relatively modest 12-15 grains of 3f 777 in my brass 1851 and 18-20 in the brass 1860.

I commonly use 24 grains of 3f 777 (a 38 special case full) in my steel 44 caliber pistols, and 18-20 in my steel 1851.

Regarding the 2f vs 3f, you're going to get less pressure and less velocity with 2f... shoot it up if you've got it, but it's meant for use in a firearm with a longer barrel... You want slower powder in a rifle to accelerates the ball all the way to the muzzle... any sort of a heavy load using 2f will almost certainly be throwing unburned powder on the ground in front of your shooting station.
 
Thanks Smokin Gun. I won't go anywhere near 28 grains of 777, but if Ferrari is having no problems with 12-15 grains in his brass framed guns, I'll stay in that range.

I'd been wondering what the difference is between FFFg and FFg so thanks for the explanation, Ferrari.

Since FFg produces less pressure than FFFg does in a revolver, then 12-15 grains of FFg should be even less dangerous to my brass frame than 12-15 grains of FFFg would be.

I really appreciate the information. Thank you both. I think I've got the picture now.
