(mods- feel free to move if there is a better section) This past weekend I went to my favorite ridge-top to sight in a new 22lr upper/scope combo and zero an older .223 upper/scope (same lower). I got the 22lr sighed in just fine at 50yards but when I switched to the .223, well things just stopped making sense. After finally getting on paper, shots were just all over the place and inconsistent (high, low, far right, waay far left, etc). Didn't matter if I was at 100 yards or 50. I suspect my (Nikon) scope has gone wonky on me but I would like to retest under better conditions before contacting Nikon for repair service. Ideally I'd like to strap it down to a proper sled at a range and do some groups, but all I have a a basic sight-vice along with folding table & chairs, basic spotting scope and no range membership. Anyone willing to help me out? Maybe in return the favor in beer or computer work?
