I've finally finished off my stash of old powder - I've got about 200 rounds worth of Solo 1250 to load in .40 S&W and that's it, I'll be completely out of pistol powder. I want to order an eight-pound jug of a medium-speed powder and want to try something new, or at least new to me.
What I'm looking for is a powder that will work well in several calibers that is not Unique:
9x19 +P with 124 FMJs
.38 Special +P and .357 Magnum with 158 coated lead
.40 S&W with 180 coated lead
.41 Magnum with 210 coated lead
.44 Special and Magnum with 240 coated lead
.45 ACP with 230 coated lead
I want to approximate factory loads in the defensive calibers (9x19, .38 Special, .40 S&W, 45 ACP) and hit midrange velocities (1000-1100 fps) in the Magnums. My main beef with Unique is how it meters, so I want something that meters well in a Dillon RL550. Other qualities I'm looking for are clean burning, relatively cool burning - doing Bill Drills with a revolver with ammo loaded with Titegroup made this a requirement - and relatively low flash.
Perusing the powder manufacturer's websites shows the following powders to be possibilities based on published data:
BE-86
W244
W572
CFE Pistol
Silhouette
AA#5
I'd appreciate experience-based recommendations. Thanks!
