I have an AR-30 in .338 Lapua (10min sight base) with a Millett LRS-1 scope using the factory rings (these are very high rings my scope was 2.7" above center bore) that came with the scope. Believe it or not, that $500.00 scope has gotten me out to 1800 yards more than once, but, that's about it.
The scope touts 140 MOA of elevation adjustment. For my rifle to be Zero'd at 100yds with the factory rings, I had to dial up 4 full rotations, each rotation contains 15MOA, so that's right at 60MOA of elevation dialed up just to get me Zero'd. Seemed a bit much, so I did some reading and 'thought' I learned that the higher your rings hold your scope above center bore, the more elevation in your scope you eat/sacrifice to get yourself Zero'd. (do I have that right?).
Point?
I just got and installed a set of Low rings from Millett. Dropped the height of the scope a full 1/2 inch closer to center bore. Since I lost my zero by removing the scope & rings and 'thought' I'd be dialing down in elevation anyway (from where I was), so I just said hell with it and dialed my elevation touret all the way down and bottomed it out and figured I'd just dial up to 1 full rotation to get a Zero, rather than 4 full rotations (and eat up 60 MOA).
The outcome is that when I went to the range today to re-zero the rifle, turns out I ended up dialing all the way back up to that 4th full rotation of the elevation touret to get my zero, so it would seem that I'm still eating all that MOA, so of the 140 the scope has, I'm using 60, just to get a Zero, so that only leaves me with 80MOA (or thereabouts), so I have the same problem of maxing out that I did before I got the lower rings. Scope now sits 2.2" above center bore rather than 2.7" with the other rings.
Am I missing something? Is my understanding of how that works just bass ackwards?
Sorry for the long read. Any info you'd be willing to provide to help me understand would be greatly appreciated.
Thanks for reading if you did and thanks in advance for responding.
