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)

That said, the .44Spec is right up their too... but the .45 Colt is still the king.
