Warne 200M permanent rings

[KenC]

The alloy rings on my 300WM were not doing the job, so I moved up to Warne 200M steel rings.

My scope barrel must be slightly undersized because the top halves of the rings meet before I am anywhere near the recommended 25 lb-in torque on the screws.

Warne says that is OK, which is clearly incorrect, and that padding might damage the scope, which is also probably incorrect.

What is the best material to pad the rings with?

My first instinct is synthetic felt, which compresses 75%, with a dab of rubber cement to hold it in place for the tightening.

My Warne rings also meet before reaching torque value. So far they have been fine on my 7 rem mag. I would suggest following warnes instructions for now and contacting them again if there is any further issue.

Their torque spec is higher than other rings, and they are steel. I get the feeling you'll crush your scope tube if you pad them at all.

Definitely don’t use felt if you feel the need to “pad” them. I’d suggest a strip cut from a milk carton if you insist, but Warne rings have yet to fail me.

I still don't see the logic of this. I don't see how say 2mm of felt would cause the steel rings to crush an alloy tube if on a slightly larger alloy tube that does not cause the tops to meet 25 in-lbs of torque will allegedly not cause crushing.

The only way this makes a little sense is if the rings are so close to round that the pressure on the sides of the tube causes the top and bottom to bulge but they have no place to go. I don't see have some felt on the sides would change this result.

If youydo it, im interested in the results.

Ive seen a number of scopes squished by aluminum rings which will start to give before the scope tube. That makes me leary of putting any inserts in rings that weren't designed for them.
