Triple Seven Powder
« on: August 05, 2016, 03:08:53 PM »
I was going to add this to a previous topic but the banner that appeared said I should start a new one. I read a lot of responses that you should decrease the load by at least 10%. Hell, I just load like normal and everything appears to be fine. There is a slightly stronger "crack" when I load the standard 30 grain in the .44, but the sighting and point of impact is pretty consistent. Anyway, I enjoy this powder because cleanup is a breeze. No fancy solvents, just water...H20 or di- hydrogen oxide does the job. The fouling is easily dealt with and the wife does not scream at me to "take that smelly thing outside." Win/win.  By the way, I got a new 1858 Remington for my wife. I think I got the better bargain.  {?|

Is it odd my wife doesn't complain about oil smells?  Then again, as a child she helped her father make smoke sticks and then as an adult cut, bent, and welded steel.

the approximate 10% reduction has nothing to do with safety.
Rather since the powder is a bit more "energetic" to get approximately the same
fps and trajectory and ft# of energy  which are all interdependent on each other
then they recommend the reduction.
But like you I just go ahead and load normally  and haven't really noticed any difference.
Just need to learn how and where your gun shoots with different loads and powders and projectile weights.

BP Jim -- Hi. What DD said.

15% actually.  That used to spook me. I didn't want to get blew up. The boys here said na, don’t worry about it and explained T7 properties on that thread you were probably referring to.  I’ll use 30 grains in a .44 anytime now and get fine safe results. 

It’s hot stuff though.  T7 may be the wrong powder to use for experimenting with how much you can cram in.  For a stout load one may rarely exceed 35 grains of anything anyway

I agree with what DD and G-Dog said.   Unless you want to duplicate the ballistics of a particular load, just use the same measured volume as you would use with black powder or other substitutes.  30 grains of any of it will be fine and safe in any STEEL framed gun.   Now, if you are loading it into a brass framed gun, I would not go over 25 grains, and probably use around 20 grains for my every day loads.  I am assuming that you are talking about a 44 caliber revolver.

@Prospector: Yep, all my BP revolvers are steel frames. I once ordered a fancy nickel plated engraved revolver from Cabelas and found out that it was a brass frame. I sent that puppy back post haste.

Hi Jim, yes T7 is the most energetic propellant that can be used in BP firearms. The only negative I have ever seen for this power is that it is more difficult to ignite than BP and that it may leave a ring of debris in the chamber that is extremely difficult to remove. I have seen reports of it going bad when loaded for an extended period, but my neighbor that kept his 1858 loaded with T7 for over a year had every chamber fire, with authority.

Regards,
Richard

You did the right thing on that one.  If a particular brasser is historically accurate then well and good.  Otherwise, I'll pass on brass.

I have been using 777 since it first came out.
Got rid of all other powders.

I love the stuff. it is SO clean and definitely gives more bang for your buck in volume for volume charges the same as 3ffg. Thing is I brought some from the England to Spain this year and I can't buy any more here because it's not available. Otherwise as a dyed in the wool non traditionalist who hates cleaning guns I would not use anything else.

tried T7 several times and between myself and co-workers have experienced several FTFs with Rem &/or CCI caps & 777.
still wondering about the long term effects of citric acid base on gun metal......remember, Pyrodex was origionally advertised as "less corrosive" too.

I'll stick with real black....at least I know what it does and how it shoots......and that it goes BANG w/o fail.

think about this........BP substitutes are called "safety powders" because they're harder to ignite......

In that respect it's just like black powder then.  Water has been the solvent of choice for BP for hundreds of years.

I get a crud ring with BP too.  I notice it in the 50 cal rifle when swabbing between shots.  It's difficult to get the patch back up from the bottom, past the crud ring, until I've gone past it once or twice with a spit patch.

I haven't used a lot of T7, and mostly I used it in revolvers, but so far it has ignited just fine.  I'd have to shoot a lot more of it to have much of an opinion.

I don't use it. I can't justify the cost. I can have Swiss shipped for almost the same amount of money. As far as subs go I like Pyrodex. It may not be less corrosive than black but it's certainly not any more corrosive than black.

Don't know (hopefully shall find out soon,) 'cause I bought a lb of Triple Se7en out at Gander Mountain (one of the few local places that carry it - percussion guns don't have many fans along the border, no one hardly shoots for "sport" here)!
                                      Basically bought it 'cause I wanted as much "oomph" behind that 240 grain bullet y'alls tired of hearing about (did buy a .451" sizer for them, only have three of my 6 cylinders bored to .4535" to accept those big honking Kaido bullets,) and figured that 777 was the way to get as much impact energy out of them that they could deliver!
                                                     Thinking of starting @ 25 grains, wad (maybe 2 wads at lower 777 amounts,) and bullet, and basically shoot about 6 cylinders from bench-rest at 50', and go up on powder from there (see if any offers significantly better groups than others)!

I'd be interested, Fogey, in learning the results of your upcoming experiments.
