Chris would you care to expound a bit on using the DZ mounts on the MVA scope?

Yessir!

I put them on my 23" MVA scope last year. It was pretty easy to do, but there were a couple of gotchas. First is that the rib on the MVA scope was on the top, but the DZ mounts want it on the bottom so you have to turn it upside down. I use a centerless mil dot so if I didn't want that to be upside down, I had to remove the reticule and flip it. That's pretty easy to do though. Second is that I had to put much taller scope blocks on. I don't remember the height of the MVA std rear block, but I went to a 0.375" rear on my Borchardt. This means no more shooting at under 200 yards. The closest I shoot for practice is 200m and I use 0.010" elevation. For 1000 yards in Byers I used about 0.358" and Phoenix about 0.383" depending on the time of day of course.

There were only 2 problems I have run into so far. First was that the scope didn't slide as nicely as it used too. Eron told me to look for a burr in the front mount on the cop that rides the rib. He was pretty much correct as I had to clean that up with a small grinding stone.
The second problem only occurred after I had used it for a while and I noticed it by accident. When I slide the scope back after shooting it, the windage knob rotates as the scope tube moves! This bit me on day one once or twice at Phoenix. I happened to mention it to Dave Gullo and he said "did you tighten the screw in the rear mount?". I said "what screw?" :-) :-). Well that fixed it perfectly.

I really like the mounts a lot, but wonder if I should have stuck with the MVA front mount.

I noticed that Kenny had a 23" MVA on his Tollofson rifle but had swapped in a B5 rear mount. This might also be a good thing. It doesn't have quite the elevation range as the DZ mount though.

Thanks Chris. I have the MVA #2 mounts the worst part with those is having to change that rear block. They provide 3 different heights. Doesn't matter much until you get to a gong match what you rotate around to different yardages.
Have also heard thru the moccasin telegraph they are working on a mount similar to the DZ, that would use just the fixed rear base.

Does the windage zero change when you swap blocks?

I am happy that I can go from 200-1000 without swapping blocks. Those mounts go to 0.450 I think so in theory I could go with a little shorter rear block. Currently I think my scope should top out at about 1100 yards with Phoenix air density, and just a touch further at higher altitudes.

Oh, you might also want to check with Robert and Eron to get their thoughts on the DZ setup.

I have not messed with the block changing,yet, so couldn't say if the windage would shift

Chris my windage changes using the same blocks when I pull the scope off and later put it back on. It will be off slightly.
The thing that bothered me when I first got the DZ scope and mounts is the windage is reversed from the MVA sights. When changing the windage for right the knob has to be turned down(left) just the opposite of the MVA.
The MAV front mount is nice if you need extra windage for the Montana winds but you also need a higher rear block because the MAV mount is higher up because of the wind gauge front mount.
