Looking at the three screw bedding method, I can well believe the torque setting on the screws mater. On the Winchester model 70 of mid 1970’s vintage, this is true as well. It relates to the middle screw, if this is over-tightened the action will be “flexed” and you will get wild shots. On that rifle the key to getting it to shoot well is to tighten both the front rear to factory spec, and then just tighten up the middle screw until it is snug. This was true of any of the rifles with factory bedding, with or without a surface expoxy bedding.

To avoid these problems in the mid 1970s pillar bedding was introduced. Correctly set up, the aluminum pillars eliminate this problem by limiting how much the action can be “sprung” by over tightening the screws.

Does this sound correct for the L81A1? Do you know what the correct spec would be?

Many thanks for any information you can provide.

One last comment on the torque settings, I just checked the M84 MK II schematic and note that they dropped the three screw arrangement. The rear screw was dropped and only the screw in front of the trigger guard and the action ring screws were retained. Might be because of the defect noted above by MKVIIIZ
