This if at all possible! I'm using Power Pistol in my .40 right now but will probably change it up when I acquire a few more calibers. I'd prefer a single powder and that'll be my goal. Until then - its PP for me!A single common powder for all of your pistol ammunition reduces logistical complexity.
You can buy it by the 8-lb jugs.
You'll never have to dump out your powder measure when changing calibers.
You dramatically reduce potential errors.
