Update May 20, 2019. I put the rifle on paper at 200 yards today to get my zero set dead on at that range. After minor adjustments to the scope the rifle delivered 1/2 inch groups at 200 yards! As long as I do my part this rifle will deliver with the 77gr Sierra TMKs. Ten round MV was 2788 with 11.7 SD. I just ordered another 500 TMKs and 250 pieces of Starline brass. Too bad that rock chuck season only lasts for another 6 weeks.
