Ok, so I did clean and shoot for 5 rounds just to get the worst of the crud out, but that was it . Then went out to the range and put about 50-60 rounds thru it . Started shooting right around MOA and kept getting tighter as I shot . At the end of the session I was .5 MOA for 6 shot group using 44.5gr Varget under 165 interlock , same performance using that powder charge with 165 Accubond as well . Very happy with this rifles performance . No drama , .5 MOA right out of the box on the first range session , gotta love that .
