Hi Glider, I've never had that occur. One 'guess' could be that you had them 'too tight' when you reassembled last time ? On my 22lrs I only torque the action to about 20-i-p - just a bit 'past snug'. If you have a T-wrench you could experiment with that and tighter but I'd venture that 35-40 should be the max unless you see accuracy improvements as you progress.
Just my best guess, hope this helps.
