I finally took my repro K98 sniper out to play. The snow is pretty much gone and the temp was in the high '40's, spring is coming fast. W/ the scope set at 100 meters, I was 1 foot low. That made me a little unhappy. Windage was dead on. I dialed it up to 400 meters to be on at 100 meters. I was shooting Prvi 196gr sp ammo. There was no real recoil to speak of. A good push, but not the shoulder hammering I was expecting. Even at the 400 meter setting I was 2" low. The reticule was in the top 1/3 of the glass when set at 100, came closer to the center of the picture at 400. When I got home I took a hard look at the Zielvier scope to figure out how to set the cam correctly. It has a focus knob on top of the turret. I had to reset the cam on both my Hensoldt Z24 and Ajack, so it had to be the same principal. I drove the pin that holds the focus adjustment out, removed the 3 screws that hold the dial down and had her finished in a few minutes. I'll lock her down on the next trip and really fine tune her. It was really very simple overall. A few measurements using only the cam and adjusting ring, made the adjustment to the ring and I was in business. She now stops dead on 800, were she should be. I can adjust her further with little effort when I fine tune her. The Germans had it right in the design of the Zielvier, Ajack and Hensoldt, that is for sure. It so simple as even a math deficient person like myself could figure it out in just a few minutes. I am very stoked about this build. It is meeting all my expectations. I'm going to take out my M41b, PU 91/30 and K98 high turret on my next trip.
