I bet that was fun. I struggle zeroing this optic when I haven't picked it up in awhile. It's a little challenging!</div></div>
It was harder than you think, because it was the first time we saw them when we were at the range. The 2112's went all over the world swapping out the rings and scopes from the Redfield 3x9's.
I think I did 5 of our 8, and a couple from another Bn in the same situation.
The Unertl had, as I recall, just a allen screw in the center of the turret knob, with no cap, to adjust the elevation and deflection, and you could do it at any range from 100 to 1000 yds. After you zeroed it that way, with no marks like on a standard, typical scope, you were able to use the elevation and windage knobs, and the fine tune below the elevation turret, for your range adjustment, compensation for altitude, ammo, and temp, and for windage and lead.
It took a little while to do it, but I was just out of the school and a sharp tack anyway, so I got it pretty fast.
After everybody came back we all went back to the range to adjust our own ourselves. To be honest, there wasn't much for them to move, because proper sight picture should be the same for everybody. they just moved a few inches or so at 500, so we could all shoot the spindle out of a spotter disk about 25% of the time. And that spindle was a little over .30", so we shot around 1 1/2 inch groups at 500.
i had two different guys I worked with as partners (we all had 2 that each were familiar with each sniper and could serve easily and comfortably with as a parnter) One was a big Cornfed guy about 3 inches taller than me, and the other was a little navajo indian. We all shot each others rifles without any change or adjustment. We could swap between us, even with the physical and height differences, and still shot the same zero, as any good shooter should.
That Unertl was very sophisticated, and very cutting edge at the time. It was designed and built to specs made by USMC snipers, and the USMC went specifically to Unertl, because of the relationship back in the 30's and 40's with the Springfield 03 Match and Sniper rifles of WW II. There was no open bid for the contract.
