I got a pound of Pro Reach when a neighbor friend died. I have tried to sell/trade it, but no takers, so I'll use it. Is there any data for it in handguns?

Accurate 7, pro reach, longshot in order on burn rate. Shouldnt be hard to work up using 7 as a start.

I figured if I used Longshot data, I would be safe. I'm not sure if it matters about extruded vs other and single base vs double based powders.
