Scope Mounting

[tomcat818]

How much gap are you seeing between the caps and the base mounts after fully the caps screws are fully torqued? I have seen a one piece (IIRC Talley) not hold up on a 300WM with a lighter scope than you'e using went to rail and separate rings problem solved. Definitely seems to be a lack of precise fit between tube and rings. Rick's suggestion might be the only way to rectify the situation.

@Allen Kitts Here you go…..I've done this to many scope rings with excellent results. It explains the scope ring bedding process towards the end of the article. @Rick Richard was 'dead on'…..as usual.

Make sure there is space between the rings when tightened.

Permatex Black Gasket cement works great. Acts like heavy rubber cement. Goes on easy, squeezes to ultra-thin film. Comes right off when you de-mount the scope - and no scratches from the rings. I'm not a smith - I just play one on LRH - BUT - I've had 3 different smiths show me this trick on guns they built for me. I highly recommend it. Plus - there is no downside.

Hate the idea of grinding the ring surfaces.....ouch!

For clarity - the permatex is spread on the inside of both sides of the ring. Torque it down, wipe off the excess - looks great - works great. Easy Peasy....

More clarity - the vast majority of scope slippage is a friction problem, not a screw problem. You can blue or red locktite the screws and the scope can/will still slip.

What torque value did you use on the ring caps, Allen?

Thanks!

I will have to look back in my book. I got the info from Hawkins.

Midway or many small shops. I use it on my scopes on magnums. I'm not shy with torquing down scopes but in my experience a few have needed a little extra love. The rosin works.

Is there a specific type of rosin to get.

Something tells me these one piece rings would do the trick. Beeefy!
