Yes I do have experience with the standard PM II 3-20, in fact, it was my very first Schmidt and I absolutely loved it, just wasn't a fan of the reticle (H2CMR). I like it more than the Ultra Short as I believe it performs better optically. If you have found a PM II 3-20 for $2200 and like the reticle I would jump all over that! In fact, if you decide not to, send me a PM with the link as I would be interestedI like the 4-20 range too. Do you have time behind a S&B 3-20x50 PMII? I'm talking about the regular model, not the U-S. If a guy could score a gently used example for @ $2.2K, would it be worth consideration? Do you know if it tunnels at low mag like other PMII models? Seems like this S&B might be the goldilocks scope I'm looking for.
Oh, and TP is right, it does not tunnel. I believe the PMII 5-25 is the only Schmidt design that does tunnel, but they have a boatload of scopes so do not quote me on that.
