Darn single shots!

I did not know that.

Having used both I have not found Pyrodex to be any more corrosive than BP as long as the gun it is used in is cleaned in a timely and proper manner.

You nailed it right there.

Sorry, but I had to do the math on this one.
So according to Andy, a modern .45-70 case is thicker than the originals, so you'll be lucky to get 45-65 gr's. of 3FG in one.
If we average that to 55gr's., we could say that the modern case only has 78.57143% of the capacity of the originals.
If the same holds true "across-the-board", then a modern .45-90 case should have a capacity of 70.714287 gr'.s.
...of course, you'll have to have the gun rechambered for the longer case, but its a means to an end.

...or just use 4198 over an 405 gr LFN bullet in the .45-70 case.

And that, Sir, is prezackly what I do. 405gr FN over 33gr of 4198.
