Do you always lap your scope rings?

[QUOTE="azsugarbear, post: 1731229, member: 4809"] I bed all my rails/bases to the action and then test run lapping on the rings once they are mounted to the rail. My theory was that most expensive rings should already show a fair amount of contact. A couple of quick passes with minimal compound reveals the high spots. I have been amazed that most times the rings (yes, even expensive ones) have only 20% to 25% contact. I lap and remove as much material as need to get upwards of 70% contact with barrel of scope. The downside of lapping is that in can sometimes leave a 'silver' band on the scope barrel when removed. I have taken to waxing the inside rings to try to avoid this. Bedding is beginning to sound easier.... I don't think these expensive rings are that bad on their own, but when you couple their small deviations with that of a base that also has its own deviations, it magnifies them to the point where minor torquing issues begin to potentially minimize the contact. Not saying this is how it is, just saying this has been my own experience. [/QUOTE]
