On the Vanguard scope is a Zeiss 3-9 with leupold mounts, the Ruger I believe has warn steel mounts with a cheap Bushnell scope. What I don't understand is when I first took the Vanguard out it shoot a 4 shot group at .75 MOA using GK 150g with 40g of IMR 3031 with a coal 2765 and I thought Great! this thing is going to be a tack driver, that was the first load I ever fired out of this rifle, just think of what I can do with other reloads or factory stuff. 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.
