I want to stock/carry just one powder for all of my arms (3F). So far I have a Ruger Old Army and .50 cal percussion Deerstalker.

I've been using T7 in my handgun and liking it a lot. I'm still breaking in my rifle with the Pyrodex I was given with my pistol, which I hate except for the smell.

I've been curious about using an energetic BP such as Swiss/Olde Eynsford.

I like the cost savings of OE, but wonder what benefit it may have over T7?

As I understand it the power generated by Swiss/OE is similar...
