Below is the test results that I posted on another forum, IMHO barnes match burners shoot as good as any bergers or Lapua scenar's that I have shot, I have about 800 rounds through my 6mm creedmoor now.
I have brass with both SRP and LRP for my 6mm creedmoor so I loaded up some identical loads with 40.5gr IMR4350 and 105gr Barnes match burners, for the small primers I used CCI 450 SRMP and for the large primers I used Fed 210 then headed off to the range to test them. The SR brass was Lapua and the LR brass was Hornady.
The rifle is an Insite arms build spec's below, the scope is a bushnell elite tactical XRS - 4.5 - 30 x 50mm FFP Mil the gun complete weighs in at 19.2 lbs.

I shot 2 groups of 5 shots each with both it's a small sample size I know but figured if there is a big difference it would show up.
CCI 450 - average velocity 3011 ES 34.7 SD 12.6 average of both groups .512"
FED 210 - average velocity 3011 ES 26.5 SD 10.15 average of both groups .521"
Strangely enough both were identical average velocity, the LRP had a better ES and SD but the groups were just a tad larger by .009" which could be the shooter
The best group was with the FED 210 @ .387 but also the worst group @ .655"
There is clearly no winner as both shot really well and stay around that magical .500" that I am looking for.
