Problem is I have never been able to duplicate this with this exact load or any other for that matter. Now I get 1.25 - 1.5 3 shot Moa with this same load. Rifle is thoroughly cleaned after every shoot. Every thing else I have shot does worse than this.
From everything I have heard on this forum from other articles I have read Vanguards are supposed to be tack drivers.
Do what I suggested, get some JB bore compound and scrub the barrel. Clean the barrel out good after doing so, then check your groups the next outing at the range. Also make sure your stock screws having backed out at all.
