In my '84, I'm using starline brass and 60gr. equivalent of American Pioneer 2f.
Since AP is a black powder substitute, that charge is by VOLUME and not weight. Over that I drop a wax paper 'wad' to keep bullet lube from contacting the powder.

It's just enough powder that a 405 gr. cast FP bullet will slightly compress the load upon seating.


The reason I use AP is because I get the safe BP pressures and all the smoke without the worries for immediate cleaning. I'm not always in a place where I can clean black powder messes the same day.
American Pioneer is very, very forgiving in that regard compared to Goex, Swissicon, or even Pyrodex for that matter. The only thing I do is drop the fired cases into a plastic peanut butter jar filled with soapy water and screw the lid down tight for transport. It makes cleaning, prep, and reloading much easier later.
