Re: Bedding a Bell & Carlson A2 stock
The age old question...to bed, or not.
Just because you have torqued your action screws, rechecked the torque, and rechecked again, the recoil will allow the action to move in the stock. Why? (several could write MULTIPLE pages on the engineering and physics of why...but in short....)
The action screws are not a tight fit in the holes of 99% of most stocks. Recoil will allow the action to move fore/aft AND left/right (slightly).
By bedding the action to the stock, you have also increased the contact area between the action and stock. More contact, generally, equals more hold (dissimilar materials, blah, blah).
If you wonder if your action is walking in your stock, fire 20, 30 rounds..and take a peak. Look at the shiny lines on the bedding block where the 1/16" contact area between the action and stock interface.
How could this be? YOU are holding the stock stationary, touch the trigger, and recoil of the action begins when the round is fired.
But I tightened the two or three screws holding the action to the stock!?!?! Excellent! There will be some slight flexing of the action screws (especially on high recoil rounds), but, more than that, the action is moving because of the ID of the action screw holes is larger than the OD of the action screws, and the small contact area between the action and stock.
