So took the FCP-SR out today and the ammo I got was American Eagle 150gr FMJ. Sadly I didn't buy any other brands. At 200 yards the rounds were literally all over the target. This was a rifle with a bipod and rear sandbag at 200 yards. I shot the rifle at 100 yards a couple months back an the rifle was a tack driver. So now I have two boxes of AE 150gr that my rifle does NOT like. 
Wondering if the 150gr might be too light for the 1:10 twist?
