Bill is right about freezing scopes. If a Leupold is having an issue with POI it is likely a loose lens assembly. Freezing it only gaurantees that there is no guarantee! A scope is a hollow tube with a system sitting on a spring and moved with 2 threaded screws. Those "screws" are your adjusters. If you picture a screw held in place with a nut welded to a unmovable piece and the end of the screw against a movable piece, when turning the screw into (clockwise) the nut the movable piece has to move. When turning the screw away from the moveable piece the spring should hold the moveable piece against the screw. If it doesn't it is likely that the lube on the moveable piece is not slippery any more. A heavier spring will move it longer after it gets sticky, but adds a lot of stress to the screw. They all require some internal clearance to enable the system to move. some have more clearance than others, that is why some scopes have more adjustment than others. The more adjustment they have the more clearance they have. The more clearance they have internally the more chance of movement when the recoil hits it.
Now all you have to do is determine which models have the most clearance. I will give you a hint - the cheaper the scope the less workmanship put into close fitting parts. A lot of the lower price scopes in bench rest are what got frozen scopes started. They had frozen scopes back in the 70's ( I am starting to sound like Paul Ross!) and when internally adjusted scopes came along it was a vast improvement in accuracy. Now scopes are being frozen and it is also supposed to be a vast improvement in accuracy?
All I can tell you is there is no warranty on a frozen, or converted Leupold scope. I can't afford to buy scopes that had a life time warranty and now don't because someone tampered with it!
