We have a winner

[Brambles]

I have been struggling to keep tight groups at longer range, it's really good at printing small groups at 100 but routinely spreads out to 1 MOA at further distances...

I played with bullet seating and was pleasantly surprised by 1/2 MOA groups at 535 yards.

Today I decided to try different primers, I was using Fed 215.... I shot in a different spot and was limited to 460 yards... Off my bipod and rear sandbag..

First group was with BR2's...POI was about .75 minutes low..but the group was amazing... 1/4 MOA....

Second group was with CCI 250's....yuck...about 1 MOA group...

Third group was with Federal GM215M primers....under 1/4 MOA and POI was back up to where it should be...

Now to stretch her legs a bit.
