Just got my Warne Maxima Rings & Bases for my BLR Lightning .270 Win. Have put it together no problems.

What is the feature with these rings that they can claim a retun to zero? The instructions tell you how to put it together but does not explain why after detachment it will return to zero.

Those of you that know these mounts can you please explain?

Thanks,

I own about two dozen Warne rings, many of them QD in both the Maxima and Premier versions. All of them return to absolute zero. All you have to do is take them off and put them back on. You may want to make sure that you push the ring as far forward on the base as it will go before tightening it down, but even if you don't it will won't matter any. The way the rings are made, especially if using Warne bases, the tollerances are very close and even after removal and reattachment the scope will be in the same relationship to the bases as it was before being removed. There is a very small amount of play between the ring and the base, hence me saying that if you push the ring forward on the base until the recoil lug/bar firmly butts agains the base face, everything will be back in perfect allignment, thereby returning to zero. Only the one side of the ring clamping system moves, so when everything is tightened back down everything is back in allignment. Even if you do not push the ring forward, the amount of play is so minor that I have found all my scopes stay in zero even if I do not push them forward. As to how long they will return to zero, let me offer a few testimonials. I have a scope on a Remington 700 BP in Maxima R&B that I remove each and every time I shoot the rifle. During the season the scope might get removed between ten and twenty times, depending on how much hunting I get to do and how many trips I take to the range before season playing with the rifle. In the several years I've owned the rifle (I've had it since the first year Remington came out with a 700 BP) I have never had to resight in after removing and replacing the scope, and it has been removed hundreds of times. The only time I have had to resight in was when switching powder charges or bullets. The Premier QD rings on the .458 and .416 Rigby all get removed fairly often, and re checked just to make sure the recoil hasn't caused the tollerances to open up. So far, after hundreds and hundreds of rounds through each, none have needed to be resighted in. Same for the Maxima QD rings on two .45-70s. I won't bore you with the QD rings on lesser recoiling rifles as it would be redundant. Good shootin' and keep your rings tight.

Hello

'Return to zero' is a relative term; there is always some small variation. I have one pair of QDs and it does seem to go back very close to where it was when I took it off. I'd like to set up a couple of scopes in those rings in order to have a spare for trips.

It is on a Weaver #74 base, which might give off a clue to some as to why it's hard to tell how close it is each time.
