I usually use leupold std rings, where you can center the windage. So yes, I do center the windage using the rear bases. Take the scope to max and go in the middle.

You can also use the burris inserts (which I hate) and center for elevation or make it so you can get max elevtion. But if you ever try this, its a job changing out the inserts. Won't waste my money on this again.

Or use biased bases like a 30MOA Picatinny.

I have seen several folks, go out and throw on a scope and then try to adjust but swear up and down the scope is junk, and turns out they didn't center the scope, and have crap rings or gun.
