I picked up a Browning A Bolt .223 last week. I put a 3x12 scope on it as soon as I got home and took it to the range yesterday. 50 yards= one holer 100 yards= not quite a one holer but if I settle in and relax, it's a hole toucher 200 yards= it's all over the damn place and 2 to 3 inches to the left of right of the bulls-eye. All of the bolts are tight, the scope is in full contact around the rings, and I get the same results from all of the amo. 55 gr Hornady, 55 gr Ultramax soft tip, and 52 gr Ultramax hollow point. I shot 170 rounds yesterday and tried everything (disassembled, cleaned, removed the scope and cleaning the rings, re-tightened everything) with no improvement. Any ideas of why it would take a **** between 100 and 200 yards?
