Help! Weaver rings sliding under magnum recoil!

I've got a BAR in 338 win mag and a Stevens 200 in 300 win mag, both with new scopes and new weaver style rings (not cheapos). Even with the scope screws being tightened as absolutely tight as I can get them, the tops of the damn rings have slid slightly off the bottoms and the scopes have slightly misaligned themselves within the first 20 rounds.

The BAR. And the scope twisted a little clockwise, so forget dialing up adjustments for longer shots...it's all Kentuky windage until I find a fix.

The Stevens 200. Significantly worse, a little worried about the doc having to pull a Leupold out of my forehead if I shoot it again...

They SEEM to have settled firmly into their current positions, and the rifles are hitting where I want them to, but it irks the hell out of me that this is going on.

So, short of buying new rings (which I don't want to do as I've somehow acquired several sets of near new weaver style rings and I want tp use them), is there anything a fellow can do to keep them gripping the scope firmly?

Thanks!

Poor contact between scope and rings is the cause,there are several suggestions in this thread : http://www.canadiangunnutz.com/forum/showthread.php?t=501451

My vote is for "lapping" the rings to improve contact area and using a powdered rosin to improve "grip". Here's a video on ring lapping, he shows a store bought lapping tool, but I got a piece of 1" precision ground shaft material from Metal Supermarket .... does the same thing, just has to be close tolerance.

I've even gone as far as to "bed" the scope in the rings with an epoxy to get 100% contact .... but sometime I can go a little overboard ! :p
 
So, after reviewing all the info in the thread posted by joe-boy (thanks!), and still wanting to find a solution that used my current hardware. I did the following.

-Take scope, rings and bases of rifle.
-Degrease everything.
-Reinstall bases on rifle with loc-tite.
-Rough up insides of rings with coarse sandpaper, working the crossways from energy created during recoil, enough to expose all bare metal, and paying particular attention to locking areas holding top of rings to bottom of rings.
-Clean/degrease rings again, and install ring bases on rifle.
-Cut two rings of latex from surgical glove thumbs and install them on scope body where rings contact (tight fit, but doable).
-Put generous amount of red loctite on ends of ring tops that grip ring bottoms, and put scope in ring bases, and slide on ring tops (difficult now that latex is there).
-Tighten ring screws as much as humanly possible while checking that scope stays aligned.
-Hope to hell this all adds up to a solid grip, or be ready to relegate all my weaver rings to the rimfire bin.

One very neat thing I did notice through this procedure was that using the latex rings on the scope body totally eliminated the clockwise slip of the scope that always plagues me when tightening up weaver scope rings. That, in and of itself, was a lesson worth the effort so far.

Wish me luck next time at the range.
 
Just replace the rings. Between gun and scope, the rings are probably one of the cheapest components. Put on some Warne rings and be done with it.

Get rid of those horrible Weavers and put on a set of Talley, Leupold or Burris. Those rings will end up crushing your scope tubes.
 
Don't forget to degrease rings and scope tube with alchohol ( isopropol not Guiness) before mounting. I just mounted a set of Burris that were almost swimming in oil in the package.

You could also try rosin, I believe I read granulated sugar works like rosin when I was making my barrel vice. Google that it might have been some other sugar form.

X3.......that's the way it is.............
