One powder that I enjoy using, shince I have a lot of it that I carry over from 12 Ga. trap loads is Green Dot powder.

In my J fram snub nose I can get a 110 JHP to go from a light 755fps to a +P 950fps.
A lead 158 will do a nice 592fps to a +P loading at 822fps

In a 686 L frame a 158 lead target load at 592fps to a hot 1281fps

With my C9 3.5" pistol a 124 FMJ starts at 916 and goes up to a nice 1133fps.

Sure there are other powders that get a few more fps out of your loads but for an all around do it all powder, this is pretty nice to have on the shelf.
