Re: scope problems
The inserts are about $10, if you need 40 moa you will need 2 sets since a set includes 5,10, and 20 moa adjustments the most you can get from 1 set would be 30 moa (approx.)
I have had them on a 300 win mag for a little over 2 years and they haven't budged at all. However Rics right from what I hear Badgers are about as solid as it gets, there have been reports of the Burris rings slipping on the big boomers.
P.S. If you go the Burris route be sure and clean all the oil off the rings AND inserts, less chance of slipping that way.
Ignorance can be treated with education, sadly there is no cure for stupidity.
