I agree with most on here, when i get a new rifle, I might spend money on components and thats all. I try every combo, looking for accuracy trends, changing only 1 component at a time. I also check pressure points on the barrel, scope and mounts, this costs nothing. The next thing I would spend money on, if I hadn't already done so, is on a proper rifle rest and proper leather sandbags fitted, fore and aft. Better optics would come next, with a new barrel,last!
