I am a Leupold fan as well, have been for 25 years. If you use big scopes like 30mm tubes, NightForce 34 mm and Mark 4 30mm on little bitty rings , etc, they have weight and if you use them on heavy recoil guns it may tend to be off a little compared to Mark 4 / heavy duty rings which holds them solid. Go on your favorite guided hunt and bang the gun / scope around in your truck or accidentally hit the door on your way in the blind, drop the gun on the floor and then you will worry if you will hit that deer at 300 yards or not. I never had my scope go off target with Mark 4 rings. I don't use Mark 4 rings on my low recoil guns, they are not needed. I have had 30mm scopes on Picatinny / Burris/ Leupold regular rings and accidentally banged them around on a hunt and was a bit off by a few inches at 300 yards.
A side note, if you are not a tackdriver, then its not needed for solid Mark 4 rings on heavy recoil guns. I put 5 shots into one little bitty hole at 100 yards and want the best. I use heavy duty rings on all of my long range benchrest guns, heavy recoil or not and shoot up to a mile. I have been reloading for 30 years. Not to rain on your parade but since your opinion differs from me,,,, I stand by my opinions because I seen it happen. I respect your opinions, its no problem. Picture down here is what I always like to do, its why I never missed a deer at extreme range,,,,yet.
Never used the new Burris offset inserts, but looks nice compared to the older rings I have used that is hard to align sometimes. Just saw the link.
