Browning X-bolt Max LR action screws coming loose

[cKnob01]

First post on rokslide (“long time lurker”). I bought a Browning Xbolt max lr in 300prc about a year ago. I’ve put about 250 rounds through it. I’ve taken the stock off several times to add arca rail, change the trigger, and some other various reasons. But I had never noticed until recently that the actions screws continually loosen over time. The stock does not have pillars but it is bedded from factory. so I’ve read in several places to torque them down to 30-35 lbs. I’ve now gone all the way up to 45 pounds and they are still coming loose after a box or so of ammo. Any suggestions? Anyone else have this problem? Not sure if I want to be putting thread lock in the action threads.
