Leupolds are great scopes, however they are not known for having much vertical crosshair adjustment. I came across this one time when I took my .270 out to a 1000 yard range. My groups were three or four feet low at maximum adjustment. I happened to have my toolbox in the truck so this is what I did.

After a little quick algebra, I determined that a .010" shim under the scope inside the rear ring would give me the proper center I needed. (it sounds like you need something in the front ring) I cut a 1/4" piece off of the .010" shim in my feeler guage set and installed it returned it to center adjustment and whaalaa, with only one adjustment I was getting repeated hits on an 8 1/2" x 11" sheet of paper at 1000 yards.

Some folks say you shouldn't do this, that it could damage the scope, but as an experienced mechanical engineer and journeyman machinist I can tell you that this amount of shimming is within the tolerance stack ups of the firearm, mount, rings, and scope tube. I later removed the shim and didn't have so much as a mark on my scope.

I'll run the numbers for you if you decide you want to give it a try to get through this season. I'll need to know how high or low you are hitting at a given distance, and the distance between the rings.
