Right on Hired Gun..., great info!!
That is how I ended up with the High Rings for my 700 BDL Varmint. The high rings worked out perfectly for me as far as line of sight goes with my stock BDL comb. Problem is that Leupolds "Mount Selector" does not distinguish between "Sporter, "Varmint, and/or Heavy Barre contours" for those who want a "low as possible" set up!! Some shooters are willing to sacrifice "Optimum line of sight" for "low as possible" optic mounting hoping to squeeze out the last possible drop of accuracy as related to the mounting of their Optic!
If I was a "low as possible" kinda'guy (Which I used to be.., but now I opt for comfort!!!) I could probably have gotten away with Medium Height rings with my set-up, but I don't know that for sure. I do know however that the "Low" 30mm DD rings I had luying around from days gone by did not allow enough clearance for my VX-III 8.5-25x50mm LRT !! /ubbthreads/images/graemlins/frown.gif
