I've always read that whatever volume of Black Powder fits in the cylinder, with the ball seated so as not to interfere with cylinder rotation, is OK. Seems simple.

But have you done it? Lots of Urban Legend stuff you can read. In a 47 Walker that is going to be well over 1000 FPS. Ruger may handle it but what is the point if its a wild load or you lead up the bore?

I loaded my ubirty 1858 with 53gn of pyrodex p and a round ball. I could barely get the ball all the way down. Put bees wax and olive oil lube over top and shot 3 cylinders like that. Didn't hurt anything dare I say it shot good. Zero leading and no damage to the gun. I'm going to bring my beater gun "pieta 1858 sheriff" and do the same test with 2f 777 tomorrow. If I don't die I'll let you know.
 
Maybe a Ruger Old Army or replica of a Colt Dragoon may be more adept for 1000 fps from a conical.
According to the P-Max Swiss powder ballistics calculator an 8” Remington/Colt should be able to achieve over 1000 fps with my 195 grn WFN bullets that’s merely 0.460” long and a 37.5 grn charge of 3F sporting grade powder. Mine has a 5.5” barrel and it shows 938 fps and a tad over another 100 fps with an 8” barrel, which seems rather high to me, but is what it calculates.
