Triple SE7EN

Recently have been trying this , FF and FFF , holy mackerel it seems to have a lot more kick.
Slowed from 30 grains to 25 in my 44 pistol , 130 to 100 in my 50 rifle , anyone else notice this?
I have always made my own powder but this is listed as plane warm water clean up and it is.
I do kinda like it but not the price.

T7 is 15% or more hotter than BP. Your best bet would be to go to Hodgdons powder page & look up the T7 loading data. 28 grains in my 44-40 Cattlemen is a handfull.

As Fingers said, 777 is a good bit hotter than true black or any of the substitutes.
As an example, my standard load of 80gr of 2fg 777 with a 300gr sabot in my rifle is the equivilent of 90gr of Pyro RS or 105gr of 2fg American Pioneer (Shockeys, CleanShot, or whatever else it's been called). This produces 1500fps at the muzzle with a barrel of 22" length.

For my 1858Rem, I've dropped from a full 30gr load of 3fg black to 25gr of 3fg 777. What you have to watch out for is loading consistency, 777 seems to pack really well so can be over-compressed while loading...................this hasn't been any issue with my rifle shooting, but I've definitely noticed it with the pistol.

Here's the T7 loading data link:

http://www.hodgdon.com/ml-warning.html when you go there, check the box and click on the 'Get Muzzleloading Data' block which will open the .pdf file. The C&B and cartidge data is on page 13 of the .pdf file

Trying to get my ROA ready to go

Managed to find some Hornady .457 balls, no percussion caps. Correct me if wrong but I believe the ROA uses the #11 cap? Correct?
I would really like to avoid a BP load that kick any more than 45LC/44 special and one that would require the use of any filler at all.
I would like to use the 777 but can one do so at 20gr in the ROA or 1858 and not use filler- in other words just a straight up 20 gr, wad and then ball just below chamber depth and go for the smoke.
I think but do not know what problems evolve if the ball is seated deeper because of a reduced BP load or whatever powder used. On some level I realize that leaving any empty space between the wad and the ball wouldn't be a good idea.

Oldfalguy -

You would have better luck getting answers if you started a new thread with your questions, instead of tacking them on to some other guy's thread. It's a bit impolite to 'hijack' somebody else's thread, and you'll only get a limited number of people reading your post.

Cap sizes are difficult to specify. First, there's no standard for sizes; CCI No. 10's are not the same size as Remington No. 10's, for instance, and they can vary even within a given brand and size. My ROA uses Remington No. 10's best, but even the Remington No. 11 and RWS 1075's will work. Others have had different results, finding the CCI's work better. The only thing you can do is buy some and try them.

Caps are difficult to buy via mail order as most places will charge you a $20 hazardous materials shipping fee on your order.

Recoil with any black powder load will be very different than with smokeless powders. It's more of a push than a recoil; you don't need to reduce your loads for the sake of reduced recoil.

The projectile MUST be seated on the powder. It is quite dangerous to leave an air gap between powder and ball.

Some folks claim there is an increase in accuracy when using filler for the purpose of seating the ball near the chamber mouth. However, that advantage is not large; many of us can't shoot well enough to notice it. I suggest you can do very well without worrying about seating the ball near the chamber mouth when just starting out; once you've gotten some experience you might try out the filler and see if you can detect any advantage.

The ROA can seat the ball on a 20 gr charge of powder. The ball will be deep in the chamber, but as mentioned above, don't be concerned about that.

Mykeal, I 'll back you 100% on the ball to chamber depth making little or no differance in accuracy. I've even tried Puff-lon which is made as a graphite filler with poor results compared to lube pills or naked.
And you already know my ill unfaded feelings for 777 in a C&B Revolver.

Changed over from Pyrodex the year after it came out and never looked back. Zero problems, easy cleaning, and near 100% reliability! If we'd had this stuff 20 years ago, I could have spared the sale and trade of several pretty front-stuffers.

I don't shoot much and I've never used 777. Pyrodex mostly and a little BP. I might use BP more if I could find it locally. Seems to me that 777 is more trouble than it's worth.

A friend just gave me a can of GOEX, almost full. Looks like it's from the '80s.
