I bought a new RA 308 left hand bolt. I had heard it was very accurate. My gun however is anything but. I received the rifle and installed a new set of Burris steel rings. I then bought a new Nikon 3x9x40 scope and mounted it up. Loaded up some 150gr over H414 and 150 gr over H335 and took it to the range. Zeroed it at 50 feet then went out to 100 yards. Now my zero at 50 feet was two shots so no groupings. At 100 yards first shot was not printed on 10x15 target. Moved right to edge of ring and shot, printed about 3 inch high and 2 inch left. Adjusted and shot and hit about 2 inch high and 2 inch left. Adjusted and hit close to center. Shot second group and hit all over the place holding on center. I use a gun rest that holds the front and back of the rifle. I shot about 50 rounds and it was all over the place center, 6 inch high 6 inch low left right.
I thought it may be a bad scope. bought a new Nikon 4x12x40 and checked to make sure the screws were tight. All was tight on rails and rings. Mounted the new Nikon scope and loaded up some more of the same ammo and took some Perfecta [not the best ammo but I can hit 3 inch groups at 200 with my M1A all day long. ] Same deal shot at 50 yds and it hit high left adjusted and was dead center. shot a third time to see where it hit at 50 feet after adjusting and it hit way high. I did not adjust but went out to 100 yards. It did the same thing it did before all over the place high low left right center. I am down to it has to be the gun.
