In 2011 when I built my first 6.5Creedmoor I ran a test between Fed210, Fed210M, CCI200 & CCI BR2.
The test involved at least 50 rounds of each primer type , tuned with H4350 in Horn brass & Berger140vld.
From that test I decided that for Me I was just fine running regular Fed210 or CCI200 ( these did have slightly different tune per type but shot equally consistent ). There was not enough of a consistent advantage for Me to run either version of the " Match " primers..
In my current 308 I run CCI200 My 6mmCreed barrel ( that was just retired ) ran WLR primers & Current6.5 Creedmoor barrel I run CCI#41 ( small pocket brass ). Non of these are " Match " primers
Average vertical dispersion at 1000yds for all 3 has been less than 4"
YMMV
Hope this helps!
