Mostly WIN231/HP38 (same thing). Also use Unique, Titegroup, Zip, Bullseye, couple others. Trailboss for any cowboy stuff - though it is dirty. WIN296 for magnums and 300AAC.It is a simple question for me. I love bullseye. I've used it since the 80s and have worked up so many good shooting loads with it that I could feed just about all my handguns with it. So many accurate loads can be had with it that I think it is the best powder of them all. So curious if there are new powders out there that others feel is better than bullseye?
Rounds I load most are:
3. 38 super
4. 38 special
5. 380 auto
I keep my eyes open, spend time (too much, probably) at the range, and buy stuff that others get rid of. If you aren't doing precision shooting, most any appropriate powder works. Load data available from the manufacturers or Ammoguide.
I don't overthink it too much. I've never really had accuracy issues with any powder.
