I've shot blackpowder for years through my T/C Hawken. I would like to try some triple 7, but I am confused to whether or not if I can load it equally to BP. For example, I currently shoot 90 grains of BP, can I safely shoot 90 grains of 777? I believe it is a hotter powder that will increase pressure, and I do not want to damage my rifle.
 
It wont damage your rifle. However the pressure will be slightly higher. Typical rule of thumb is to reduce your load by 10%. So 82 grains is what you would use. However that has to be tailored. Meaning you may want to start out somewhere at 70 grains 777 shoot and see how accurate it is at a given range. then after shooting a couple rounds. Increase to 75 then 80 to see where the best accuracy is for your rifle.
 
You will really like Triple Seven.Reduce your load by 15%. Adjust as you see fit. You will find the instructions on the Triple Seven powder container....
 
I first started shooting my Remington 58 with 777 and when I posted the video several of the other folks commented that it seemed to kick a lot. I was using 30grs and the gun handled it just fine. I've backed it down to 15 and it still shoots fine and is accurate as heck.

Ok, now I'm really confused..

I have a Pietta 1858 .44 Revolver. From Pietta's information sheet it says: to use 12-15gr of FFF BP.


But Hodgdon information sheet says:
44 cal. 1858 Rem. Steel Frame 20gr. 25gr.
454 Hdy. RB Ox-Yoke W/Wad 536 763

I though that you used 15% less volume with the 777.


I've not got all my supplies together yet, so I have not had a chance to even load it, much less fire it..
 
As much as I hate to counsel ignoring a manufacturer's data sheet, the Pietta recommendation is of little use. The gun is capable of safely firing all the powder you can stuff in the chamber. The most accurate load will be somewhat less than a full chamber, however, probably more like the Hodgdon numbers.
 
Couple of things: First off, don't confuse volume and weight. DO NOT put 90 grains of 777 in a ML. Do set your measure to 90 grains BP and then use that much 777. A friend recently tried a 150(measured on a scale) grain load of APP. He said it sure did kick!

Second, for some reason Pietta recommends that 12-15 grain load for about everything they make. Don't know why, but they do. Legal stuff I reckon. They are safe with heavier loads.
 
You can really change the pressure levels with heavy compression on some of the subs like APP. However 777 is the only powder I'd worry about stressing a Cap & Ball excessively and those being the Colt's revolvers. I have heard from a reliable source of one Walker being stoked with 777 and having the barrel assembly go down range leaving the shooter with the grip & cylinder in his hand. Last I heard his gunsmith was going to try to salvage it as some kind of pepperbox. The gun gave at the wedge cutout on the cylinder pin. The Remingtons will likely hold up with a steady diet of 30grs (vol) of 777 but I wouldn't do it with a Colt. A brass framed Colt would be shot loose in no time.

I have not noticed excess loudness or recoil whenever I over charged a colt and had to shave lead off the nose to get the cylinder to rotate. That was AFTER ramming the the bullet in as hard as I could without bending the rammer. APP gets pretty hot when packed hard under heavy compression.
 
This is jus' a suggestion. If you have been usin' Black Powder, it shoots to your mark and you like your Rifle or Revolver don't go to a synthetic, especially 777 ffg, or fffg in your Revolvers. I can tell ya that I sheared the frame pins while knockin' the wedge out of a Pietta 1860 Army three rounds of 30 gr 777 ffg. I won't use it. Inaccurate in revolvers compressin' it too much is to easy, non repeatability. Tried it in 58 Rems, '51, '60, '48 Dragoon Colts... Nope ain't as good as Black Powder not near...

Your new Triple-P Loader should be able to help regulate 777 powder compression using lower charges, at least in some revolvers.
But I also realize that you prefer to use real BP. :)
 
777 is good powder but like was mentioned it is kinda sensitive on the compression it takes in that it will be inconsistent on ignition or very inconsistent on the groupings.
If the ball/bullet is just touching the 777 powder I had the best results in my CVA Bobcat in that it went BOOM every time & my groups were relatively acceptable.

Since this has some of the Pietta '58 Revolvers in it I'll put my 2 cents worth in.
My 2 Piettas "a 24 year old w/ 8" barrel & a 1 year old w/ 5.5" barrel" have had up to 42gr. FFFG Goex or Pyrodex P with a .457 142gr. Ball in the chambers & fired reliably with no ill effects to either weapon although the accuracy was not the greatest at that charge "kind of a I want the BIG BOOM effect a cupple of times" but my normal charge is between 22 - 30gr. FFFG or Pyrodex P with either the .457 142gr. Ball or my .456 220gr. Conical for both target or Hunting type loads.
 
Wow, that is some double tap! Forum been screwy lately.

777 is fine as long as you don't compress it. I just had the opportunity to use my new PPP loader, so I shot up some 777 I had. Being able to seat the ball to the exact depth on all chambers with the 777 made for some accurate shooting.

I've shot blackpowder for years through my T/C Hawken. I would like to try some triple 7, but I am confused to whether or not if I can load it equally to BP. For example, I currently shoot 90 grains of BP, can I safely shoot 90 grains of 777? I believe it is a hotter powder that will increase pressure, and I do not want to damage my rifle.

That is very close to the load I shoot in my T/C Hawken. To duplicate 90gr (vol) BP, load 77gr (vol) of 777. Just be consistent with your seating pressure, don't ram it in hard, you want the ball just touching the powder charge.
