Re: 20 MOA base.
I just had an enlightening experience with my Badger 20moa base. I have been trying to standardize all my rifles with the same style base so I could swap glass without having to adjust ring spacing or re-level reticles. Have gone to the 20moa Badgers on everything. I just purchased a target rifle from a member here with a custom 20moa rail and pulled a scope from another gun for it. With the scope zeroed at 200 on the original rifle it had the same zero, within 2 clicks windage, on the new rifle. Seems the standardizing may have more merits than I thought. BTW, the original rifle was a 6.5-.284 and the new one is .308. AG in NC
