I would print out, or save on your desktop, a powder burn rate chart. Have it with you when you are powder shopping and select a powder close to Bullseye in burn rate that you CAN find. I love BE and use it in 40SW too, but in truth, I think AA2, Red Dot, WW231, and at least a half dozen other powders would do the same thing BE does.
