I follow a similar procedure for scope mounting (standard rings, lapping rings, etc.). I would add that I center the reticle before sighting the scope in. That is to say, I turn the windage and elevation dials until they reach the end. Then I turn them through their entire range, counting the number of clicks until I reach the other end. Then I turn the dials back 1/2 the total number of clicks in their range so the reticle is "centered".
I have some questions maybe some other readers can answer:
I use standard bases because I like to be able to adjust windage without getting the reticle too far out of center. Are their any advantages to weaver style bases other than being able to move your scope back and forth if you run out of slack with the rings.
My preference is always for one-piece bases (not always available for lefty guns). Does it really make any difference, or am I just as well off with two-pieces?
I generally boresight by removing the bolt and looking downrange. Recently bought a Bushnell magnetic boresighter. It's useless! It's held on the end of the muzzle with a long magnet. How do I know if I'm boresighted for elevation? If I slide the magnet down or up 1/8", I'm off again. I try to get it level with the bell of the scope, but at best, I'm eyeballing it. And if the boresighter is canted just a little, the windage could be way off. I bought it 'cause it was less than 1/2 the cost of the cartridge-style laser boresighters. Wish I'd gotten one of them.
