I don't reload shotgun, so that aspact of usage is not relevant to me, but my four choices are WW-231, H110, WW-748 and IMR 4350. I had a very hard time leaving Unique and 2400 off this list, but for my shooting today, these are the ones.
WW-231 all standard and mid-power cartridges that i reload, 32 acp, 32 S&W long, 32-20, 32 H&R, 327, 380, 9mm, 9 mm largo, 40 S&W
