I have an Omega 50 cal. I and quite a number of others have had trouble getting on target with these Omegas , and some Encores too. I went to the Burris Sig Zee setup. I started out using the standard inserts that came with the rings ( no off-set ) . Got everything mounted up did some shooting, and ran out of adjustment way before I was even remotely close to my zero. This told me that either the original base or the gun was off . I then installed a .010 off-set on one end of the scope and .020 on the other end. I do not remember now which way I had to go as it was a couple years ago , but the point is that once I got the inserts in I set both crosshairs in the middle of their adjustment range and started shooting again. I was sighted in within 10 shots and had only moved the crosshairs a little way from center of their adjustment range.I don't understand the adjustment inserts. I have always been able to mount a scope and get elevation and windage right without running out of room. Am I missing something here?
UT, I mentioned that I bought the Posi-Align adjustment set just as a side note. After installing my Zee rings with the standard inserts that came with them, I would recommend to anyone (you too) NOT to get them until after the scope is installed and you think you need them. You probably won;t, so I would say forego the adjustment set.If I had no problems with the gun or base with running out of adjustment on my scope, when I put on these new Zee rings and a new scope can I expect to ave no problems as well?
