Been trying, on and off, to get my .243 zeroed, but struggling.
Seem to be able to get the elevation spot on, then, by trial and error, get the windage to within about 1 - 2 inches of where I want it to be. The clicks don't seem to move it a predictable amount.
So, when I try to adjust the final inch or two on the windage, lets say it's still 2 inches too far to the left, turn 8 clicks and hey-presto! the shot jumps about 2 inches too far to the right. So I try to adjust it back again and nothing happens - shot goes in same hole. So I adjust it a bit more, and suddenly it's gone too far to the left again.
In the meantime, all the fiddling about seems to affect the elevation, which creeps up a bit, so I'm back to square one.
