That's the cartridge not the rifle.

WHAT EVER,
Call them and ask yourself, unless you find out for yourself, you will not be happy, I called them and the triple 7 is for the 45-70 for use in the trapdoor,
Do you want me to give you the number as well ? maybe dial it for you ?

I would not be concerned with the load since it shows 2f at the header. Usually powder manuals list loadings for 45-70 as weak action - lever action - and strong action such as the Ruger No#1. I would think the bullet weight and lead flat point would be the guideline to stick with. As long at the compression of the charge is only .100 it is ok and I assume that is the reason for the bullet choice. No air space and no excessive compression with the ideal being the bullet seated to the powder since excessive compression causes pressure spikes. The only drawback I see using the powder is the limited load and bullet choice since they warn not to use fillers. If the load produces a 2 foot group at 100 yards then it is money wasted. Also sugar based powders form a hard fowling more so than BP making accuracy of following shots more subjective to inaccuracy unless swabbed after every shot. It's still corrosive and harder to ignite. I think it was designed more for inline muzzleloaders for increased velocity. For me the slight increase in velocity coupled with the limited loads available make it a thumbs down. The old trapdoor does very well with BP and is a proven killer of game. You can opt for different bullet weights and designs plus wads to get the best accuracy from your rifle. That's just my humble opinion.

Considering I was hitting the 12 in steel at 200 yards, I think it is plenty accurate.

Isn't Goex a higher quality powder compared to others?

12 inch hits at 200 yards ain't bad at all. I'll almost bet if you hang a bowling pin up at 200 and get that front sight dialed in it will probably hit the pin very consistently. Once you get the right load for the gun they are very accurate. Problem is not all guns like the same diet.
