Jim, I ran the same tests with CCI-300 and CCI-350 primers with Unique (and several other powders). Same conclusion as you got. Use any primer available and your fine for Unique. I'll use standard of course when I have a choice.
For example, .45 Colt
8.5g Unique, 255g SWC, CCI-300, 977fps, 17 SD, 56 ES, 15 shots
8.5g Unique, 255g SWC, CCI-350, 985fps, 21 SD, 82 ES, 15 shots
How hot, least to most: CCI-300, WLP, CCI-350 (the only three I've tested)
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
