I got to the range yesterday and tried some of the Prvi marked boxes of 75 gr HP Match. And some Black Hills 68 gr, BB.
The Prvi was fairly accurate, burned clean and functioned fine. What I got with 5 shot groups was 3-4 shots that were pretty tight with 1-2 flyers that would open a MOA group to 1.3-1.5 inches.
The BH was more consistant staying inside of an inch at 100yds from the bench with up to ten rounds with the best 100 yd 5 shot group being .48 inches center to center.
Not bad for the money for sighting in and punching paper, or even staying in the vitals of a coyote out to 200yds.
Rifle used was a J&T Marksman upper (A3 with YHM FF tube, Wilson Air guaged HBAR 1:8 SS, Vortex Flash eliminator). Tasco 6-24x set on 10x. Superior Lower with RRA 2 stage trigger. Fired from sandbags on wooden bench. 76 degrees F 68% humidity with 4-5mph cross wind.
