Triple 7 question

[ColonelTravis]

New to black powder, just got a 1847 Walker. The only thing I could find in stores near me now is Triple 7 FFG, which I have read is fine with this gun (vs FFFG). I'd like real black powder, that's tough at the moment.

Triple 7 is hotter than black powder? How/when do I take this into account when loading? If I wanted to shoot 40 grains of real black powder in the Walker, do I need to use less than 40g of Triple 7?

Thanks

I've never used it but just wanted to say congrats on grabbing a Walker. Randy Wakeman says, "Triple Seven and Black Mag3 are far hotter (or more energetic) than good old black powder, and produce higher velocities and pressures."

I was fortunate to find a supply of Swiss and that is the most energetic BP I've used, driving a .457 RB to 1282 fps with a 55gr charge of 3F.

I think you want to start triple 7 about 15% below BP max. But you may want to ask the mfr. And nice score!

What Duster said.

Hodgdon recommends a 15% reduction. A 40 grain load would be the BP equivalent of 46 grains. Being 2f it will burn a bit slower than 3f. Some folks don't follow the 15% rule, others do. I've used a lot of that stuff and it's good.

 

[45 Dragoon]

Recommendation is for equivalent to bp. Nothing wrong with using it as a direct replacement. I burned a llllllllllot of that stuff!!!! Lol

Don't over think it, if it was too dangerous to use, they wouldn't be selling it.

Thanks everyone. Can't wait to shoot this beast. It's not the most ergonomic thing out there, probably not everyone's first choice for a black powder pistol. As a Texan, I don't care! I'm all for a spectacle every now and then.

Load 40 grains friend no need to worry

40 grains in a Walker is a pipsqueak load, even with T7.

Yes it is sir, yes it is.

My 1860 armys shoot 35 grains 3f Old eyensford. I dont know if I could fit 40 though probably 37 or 38 with .457 ball

 

[J-Bar]

Hodgdon recommends avoiding compressing 777. Just eliminate air space between ball and powder, no need to crunch the projectile down hard. When using 777 for light cowboy action loads, I simply used it like regular Blackpowder. If I were going to load an antique/Damascus firearm with charges over 100 grains, I would likely calculate the 15% reduction, but geez it’s not uranium.

I never owned a Walker. I’m jealous!

You really should correct the arbor on that Walker before getting too carried away with full house loads. Ubert has never fixed the problem, this is a new Uberti? I have personally seen Walkers self destructing because of the short arbor including one of mine.

 

[Eyrie G. Dogg]

This may be off topic, or not, but why does Uberti make short arbors? Do they not agree that there is a problem?

Is the company in denial that this issue exists?

They don't see it as a problem. They see it as a benefit, being able to adjust cylinder gap with the wedge.

 

[Jackrabbit1957]

What Hawg said, which is total BS on Uberti's behalf as it leads to stretched frames and other damage from the cylinder flopping back and forth plus you get a different pistol, as far as accuracy and assembly is concerned each time you put it back together. Trust us on this one, it needs to be fixed.

I always load a 20% reduction by volume comparing 777 to 3f black powder since my chronograph shows that level of reduction to approximate black powder velocities. For the 1851 in .36, 19-20 grains of 777 replicates full chamber loads of Old Eynsford.

Yes, it's new and I will address the arbor and a few other things. Sorry about one of yours, not fun.

 

[Jackrabbit1957]

That's the reason I fix em for others, I was able to fix mine along with lots of improvements, it's a good accurate shooter.

 

[Jim Watson]

Note that 777 is a typical fake powder to be loaded by volume, not weight.

How far down will a C&B rammer push a ball over a reduced load? Or must he use non gunpowder filler?

 

[Jackrabbit1957]

Usually about 1/2 the depth of the cylinder, sometimes a third.

What do you mean by "fake"?

 

[Jim Watson]

I mean it is not black powder made out of traditional ingredients.

 

[Jackrabbit1957]

Some folks get bit by the purest bug and nothing else will do for them but the holy black. I'm happy if it goes bang and sends a ball down range. T7 is a substitute that works for me and lots of others. If it was not so expensive these days I would shoot more of it.

Its always been too expensive for me.
