Scope ring lapping

No offence Rich, but, how did this thread on a woefully overlooked scope mounting technique turn into a missle shooting match?

Now the important matter.
Yes, lapping scope rings is nessecary. 1; are the rings perfectly aligned? Probably not, any missalignment will (tweek) a scope tube to some degree causing scratches and even denting. 2; look at the inside surface of any quality set of rings and you will find machining marks, those reduce the bearing surface which contact the scope tube, that in itself is what causes slippage.
By lapping you achieve that final .0005" of alinment as well as increasing bearing surface at the same time, and it only takes 20 minutes.

like they say spend as much for the scope as you did the rifle then mount it right.

Rich, there's another tip I forgot to mention.
put a strip of electrical tape inside the ring halves about 1/4" narrower than the ring, even a lapped ring can scratch, tape also gives a bit more grip on the tube.
