Need to get your rear mount up by roughly 0.5mm or front one down by that ammount.
Sometimes swopping front and rear mounts does the trick if it is an option on your mounts.
optilocks?

Burris Signature Rings with offset inserts are an option worth considering too if you have Weaver type bases. Regards JCS

 

[ckwoodland]

thanks jcs warne mounts on weaver base on my 3006 placed thin piece of card under back mount as ejg suggested of to try it out now

One piece picatinny rail with 20moa incline would be the best option but shouldn't be necessary at all. Sounds like your current mounts need looking at as they may not be on right. Could you post details of whole setup. I would be careful shimming the rings as it will induce stress in the scope tube. Would be a shame to crimp the tube!

thanks to all have just got back from zeroing small thin card under mount job done plenty of clicks to spare thanks for the advice sd what a site

nice one maybe been better tinfoil or lead as card will get wet then back to sq /one
just my 2p worth shimming scopes has been around for years

When I had to make a shim for a base I used the alloy from a fizzy drinks tin.

​I really prefer not to shim as it means something is not right.

I really prefer not to shim as it means something is not right.

Most likely the unhelpful strain imposed on scope tube in the area of unshimed ring!

The laws of physics dictate that for there to be zero corresponding strain the ring/base subject to differential elevation needs to be milled at an angle in direct proportion to the offset.

I shimmed mine with some pieces of very thin pespex held in place with black double-sided sticky tape. Looks very neat and tidy, and seems to do the job.

 

[jcampbellsmith]

I had a shim situation and then got a set of these which don't stress the scope tube. http://www.burrisoptics.co.uk/sigrings.html Regards JCS

just been on the burris site thanks jcs think i may get a set i also think that card was not right many thanks again all what a wealth of knowlage there is on sd
