Thread: shimming scope rings confusion

I need to put shims in the rings for a tactical scope I'm fitting because I can't wind the drop any further. I'm confused! It's shooting 0.6" high of the bull's eye. Do I put a shim in the front or rear ring?

Where is your scope adjusted to, for the .6 high impact.

Is it at full up adjustment ?

Full down adjustment ?

Centred for adjustment ?

Yeah I've tried everything. Same rings work fine with a different scope. this scope is a Leupold VXII 6-18 w tactical turrets. I've even sent it to Leupold for new mildot reticle and servicing so it should all be sweet. Shimming seems the only option left and I think it should work fine.

Aah full adjustment up. So Any adjustment will make it shoot higher on the target

If you want to raise your point of impact shim the rear to lower shim the front

No it must be full adjustment down. The arrows on the turret are bloody confusing. Anti-clockwise as far as it will go which has brought the poi down until it can go no further but still .6" high

Shim the front then and yes don't glue the shim in - it wont go anywhere

Shldnt that be shim the back ?? If he cant "move the shot up" any more it means the horizontal reticle bar is fully down ...

That being the case, he needs to lift up the rear of the scope to alleviate the problem ...

I might be wrong , maybe I'm the one whos got it arse about ...

in any case, its now dinner time ...

I thought he was trying to bring the POI down and had bottomed out the elevation so therefore you would shim the front

Nah it's me who's confused everyone. I'm going to have to understand the direction on the turret otherwise hunting's gonna be disappointing to say the least.

Shim the rear

Have you tried lapping the rings ?

Theres a forum Lapping Kit somewhere ..

I Shimmed a scope ring once on advice from someone on the the forum .... I used a sliver of coke can .... worked a treat ...

I've cut shims from a V can and aralditing them in but thought I'd still lap.

Whatever you do, DON'T glue them in ... you dont need to .. they stay in just fine by themselves !!! If you glue them in you can get them out !!

Araldite is an epoxy that does not like heat and will let go when warmed up and then can be wiped up. On the other hand it is also not the best for use on a rifle if that is likely to make it warm, it will them ooze out. About 50C it starts to let go.
