From what I can understand, the main problem this caused was when dialing down, the click values were way out. When dialing up the click values were out around .5 moa at 30 moa up ?
Unless I am wrong this would suggest that when you went to dial back to your zero, you may be getting a different starting point each time when starting out ? Does that sound right ??
If this was so you would certainly be up that famous brown ( s**t) creek without a paddle !
Have not been able yet to test it yet, but will let you all know the results shortly.
