    Some are harder than others I guess, I've rounded off a few, I could probably break a bowling ball with my less than stellar mechanical skills.

    I would put a straight edge on the rail first to see how bad it is or not. If straight proceed. If not, toss it and get a brand name rail. EGW puts out some real junk from time to time.:D:D

    There are much better tools available than Craftsman, not what they were years ago.

    I can't imagine a 6x48 or an 8x40 standing up to 45-50 foot pounds. Surely they would strip. Did u mean to write 45-50 inch pounds? EGW recommends 20 inch pounds.

    Yes DEFINITELY, surprised someone didn’t catch that sooner.

    Any particular reason you're going so heavy on the torque, other than things coming loose? As already pointed out, EGW recommends 20 in-lbs, and other manufacturers (i.e. Farrell) recommend similar values - 20-25 in-lbs. That and a (small) drop of blue Loctite should be enough to hold it for a good long while - assuming the rail fits the receiver well.

    Just what you said, trying to get it to stay put. I’m only going to 20-30 inch pounds now because those #10 Torx kept breaking anyway. I’ve already bedded the high end with JB Weld and torqued down the low end to 30 in-pounds with purple loctite on them. Now I’m going to wait several days before putting in the high-end screws and I’m gonna only go 10-15 pounds on those since there’s JB Weld on that end already.

    Sounds good. I'd love to see pics of the underside of the rail after you have it all done.

    Tighten the screws and then take a hammer and your bit and give them a smack, that sets them a little deeper in the threads and then tighten some more. They shouldn't come loose. That is how I have been doing mine since I got my first Unertl scope back in the 70's

    I had the same issue with a Savage over and over. Murphy base bedded, not glued.
    It was the stainless screws. Never came loose again after they got changed.
