I use IMR 4985 in my .223, which meters well in my RCBS meter. I had also used Win 748, but I didn't think I got any better groups with that. I use H4350 in my .30-06, which does well. I use the IMR 4895 in my .30-30 and 8mm Mauser as well. I have some H335, which I was thinking about trying in my 8mm, but I am waiting until I get new sights for it, or a scope set up. For my 45 ACP - I use Unique. Its a bit dirty, but it sure makes for nice practice loads with the 185 LSWC bullets.
