4 shots won't yield a statistically valid result. Minimum test is 20 shots of each.
Kissing the rifling is a tricky load. To test primers, i would rather be 20 thou off the rifling.

I would expect the Fed 205's to do well, supposed to have an easier ignition than CCI's. Those of us shooting 308 palma brass pretty much settled on CCI 450's and Fed 205's.
I haven't tried the Fed 205's yet but planning to test them next season.

I'm trying .010" off the lands for my tests this weekend with the 80.5gr pills and BR4 primers.
