Unique is king. Well, other than Clays, Titegroup, N310 and Bullseye, it is king.
TG... with lead?
I've used Clays and liked it quite a bit for a mild 200 gr lswc load. For some reason, I never liked Bullseye... I know it was used in military .45 for many years, I just never thought it did a better job than Unique. I haven't used N310, so no comment.
