Ok, last week I bought a new Bergara Premier HMR Pro in 7PRC. I ordered 3 boxes of Hornady 180gr ELDM to break it in with. First 25 rounds best I could do is about 1.5 " MOA at 100 yards, it just would not group. I know I'm no pro, but I shoot the same range with my Fierce Carbon Rogue 300WM and shoot .75" to .50" regularly. So after doing a lot of research, I saw where others have had problems getting groups with some of these rifles and after taking the action & barrel out of the stock, they saw both lugs where the action screws bolt into covered with paint. So I took my Dremel tool and put a small wire brush on it and removed all the paint down to bare aluminum. Also removed overspray from the recoil lug receiver. Put everything back together and torqued to specs. Just shot a 5 shot group that would be 1" with 3 of the five touching. Something to check if your having group problems.
