Re: Reticle alignment
No matter the method, when finished it is still important to verify the come ups are following a vertical line. Just last evening I was checking the scope installation on my .22-.250 in preparation for winter varmint hunting. I shot a group at 200 yards, dialed up 20 MOA and shot a second group using the initial point of aim. The second group was one quarter minute of angle to the right. That's more than can be explained away by the Magnus Effect.
