Anyone use/like this stuff? Never tried it, but I am looking at suitable alternatives if I can't get real black.
 
I do.
Black Powder Substitutes are chemically formulated to be harder to ignite than Black Powder and less explosive outside the confines of a gun barrel.
Triple Seven uses sugar instead of charcoal for fuel, can draw moisture from the atmo and clump up. If I open the 777 container when needed and close tightly after, it keeps pretty well. Unlike BP, you cannot dry out clumped 777, rescreen it, and have shoot as befire in clumped.
TripleSeven requires magnum level priming for ignition and makes a good BP Cartridge propellant. Not recommended for flintlocks.
Clean up is easier than Pyrodex or Black Powder. Pyrodex is the most corrosive of the three.
 
I’ve used pounds of it in my revolvers. I prefer BP as it’s cheaper and smells better. It works great and would be what I’d use if I couldn’t get BP. I use Rem #10’s with no ignition problems.

I read long ago that with people stating issues with T7 after opening it was tossed out that maybe desiccant packs would fix this. I’ve been doing it since it surely can’t hurt, and my powder seems just as potent as it was years ago when I opened it.
 
It has been reliable in my inline . It does leave a crud ring after firing making reloading for a 2nd shot hard and almost impossible without running a damp patch down the barrel . It is said to be less corrosive than Pyrodex . I have also tried Blackhorn 209 . It doesn’t leave the crud ring , but it wasn’t always reliable in my gun and caused me to miss a nice buck . Nice for targets , but I will not hunt with it .
 
Only chain fire I ever experienced was with triple-trouble. Blew the front sight and the loading lever latch off my 1860. On the second shot of the second cylinder. Or, shot number eight. A fluke? Don't know. Shot that gun with black only for 20 years, never a chain fire, even without wads or lube. Has probably been ten years since, and never a chain fire. ? I suspect that even though it's harder to ignite, it may burn quite a bit hotter. I didn't know it had sugar in it.

Not too long ago, someone posted about 777 blowing the hammer back on their side lock, and damaging their lock. I've had dozens of hammer blow backs with rifles, if not 100. None ever damaged a lock. ? Fluke? Who knows. I'd use Pyrodex, if I HAD to, before I'd touch 777.
 
I think tripple 7 is supposed to be down loaded some too. Like if your rifle is rated at 100 grains by volume of black powder. You should run 80 grains of tripple 7 as an example. My Cva wolf is rated up to 150 grains. i run it at 100 grains of pyrodex. My neighbor borrowed mine this past season. His he forgot to clean and it pitted the the barrel. But anyways he used 80 grains of tripple 7 in it. He took at deer at 78 yards. It hit point of aim.
 
It's a bit more energetic, plus it's a finer granulation. My big problem is it clogs the gate in my Hawksley flasks. Otherwise I like the stuff.
 
Sounds like it has its plusses and minuses like most of the other alternatives (and real black for that matter). I like my Black MZ, but it is gone and the American Pioneer is a lot more than ten bucks a pound. When I run out there are certain things I don't like real black for especially (revolvers especially), so I will have to try triple 7.
 
Cowboy action shooter here. 777 is delightful in .38 Special and .357 Magnum cartridges, as well as lightly loaded 12 gauge shotshells. Load it by volume as you would any “real” black powder. I prefer real BP in percussion revolvers for more reliably fast ignition from a percussion cap. I don’t worry about it being “15%” more powerful than other powders with the small powder volumes (20-40 grains) I am dealing with. You can’t tell the difference with small powder volumes. If you are using over 100 grain powder charges and attempting precision shooting at long ranges then maybe... Otherwise, consider it another brand of blackpowder, clean your guns soon after shooting, enjoy.
 
I’m not a fan, but I stocked up since it was the ONLY powder available in my area, so now I’ll be shooting it for years whether I like it or not. In retrospect, I should have just stocked on Graff’s for cheap plinking powder and used my premium powder for carrying. 777 is the only powder that still knocks down my loading lever. It has this effect even when loaded light at 18 grains. It loosens every screw on the gun after a single cylinder. It sounds like smokeless powder, more CRACK and less BOOM. Even highly energetic black powder like Old Eynsford doesn’t do these things with full chamber loadings. I hypothesize it’s a speed of ignition difference. 777 seems to combust too quickly with too high of pressure, leading to the gun absorbing more shock than with comparable slower burning black powders operating at lower pressures, even if the velocities are similar. I’ll be shooting the rest of my stock over the next 2-3 years and sticking to the real deal after that.
 
My guess would be that it's actually a smokeless powder, with something in it that makes smoke. (the sugar?) I suppose that's true of all the substitutes.
 
Triple Seven is mixture with a separate oxidizer compound to provide oxygen to burn the fuel (sugar).

Smokeless powder starting with guncotton or nitrocellulose is a single compound, it's own source of oxygen and fuel.

Classic black powder is potassium nitrate for oxygen, charcoal made as pure carbon as possible, and sulfur as a fuel and binder for the mix.

Sulfur is also used to lower the ignition temperature of the powder, which is it's primary purpose. I make a formidable powder without the sulfur, but it takes fire to ignite it. A spark won't do.
