I haven't been shooting much as the supplies are scarce but when I have in the last several months decent groups have been scarce. I recently took my action out of the stock to find one of the action screws looser than the other. Also found the single shot follower I had JB-ed in the action had came loose. On to the scope, rings were tight to the rail but my front 2 base screws were not as tight as the rear when checked with a torque driver. I used to check these things all the time, guess I'm going to have to fire the maintenance man.

I know what you mean Dennis. That very thing has cost me a match or two and I do my best to not let it happen again. I was shocked when I found the same thing wrong with my long range benchrest rifle a few days after the match and that’s when the light came. I check those screws mentioned frequently.

Those loose screws have crept up on me also. Now I constantly grab my scope and try as hard as I can move it while watching all the attachment points.

I have been gluing my pic rails on to the receiver for a good while now, even on pinned rails, it has stopped the bulk of my problems with things coming loose, if you shoot a lot like Richard and some of the rest of us it is good insurance.
recently I had to take one off, some heat and light taps and no problem. Action screws will usually stay put IF you torque/loosen/retorque several times when the gun is new as long as it is properly bedded.
Good rings are a must on these guns, all I have used in the last few years are NightForce 6 screw ultralights, the big nut that holds them to the rail torques to 100 in-lb, I have never had these work loose, the extra clamping force of the 6 screws has never let a scope slip on my guns, can't say that for many other so called good rings.

I use the NightForce ultralights on everything that has that punch on both my ML's and centerfire, they are expensive but worth to me every penny, where do you hold back with the $ and cents and after this thread will have to check and MAINTAIN my toys!!

I have dealt with these issues in the past and can't for the life of me figure how I didn't just check these things instead of wasting powder/bullets/primers $$$ and time and frustration. I had even thought a (New) NF competition scope was faulty until I saw the owner, who let me borrow it, put it on one of his rifles and it was right on. What is memory worth? Alot when it counts. I may be getting (sometimers).

As far as rings go? My pockets are not as deep as some others So I go for the tactical type (6 screws per ring) (with the big 1/2" nut on the side clamp, that are sold by Burris, Weaver and a few others. They are meaty and have never failed me. And, if you have followed me for the past 14 years or so, you know I don't shoot "sissy" loads------ these are what I use. The rings run in the $50 - $60 dollar range for the pair. Along with the large clamping surface, I put a light coat of clear bonding agent on the clamping surface (an automotive product used to promote adhesion of paint on smooth or un-sanded surfaces) I have never had my heavy NF competition scopes slip. Like Hillbill, I Marine-Tex epoxy the base to the receiver and use larger screws to attach the base (6-48 I think). The screws I attach with blue lock-tite. BTW, I use no lock-tite on the 12 scope ring screws....reason? When you tighten them, the fact that the ends do not touch?----This kind of acts like having a spring tension---------------they never loosen!

6-48 are pretty standard, some use the larger 8-40s.

X2 ! A couple years ago I saw a video by Jeff ‘Broz’ Brozovich where he demonstrated bedding his pic rails (no release agent) to his actions with JB Quick Weld. I’ve been doing it ever since and things don’t work loose anymore. I also bed my scopes to the rings using JB Quick Weld (Hornady One Shot for release agent). Makes for near perfect tolerances and no ring marks.
