I bought another American stock at a decent price with plans on using a barrel with a different contour that may require opening up the barrel channel some. I installed my barreled action in it thinking I would start de-mudding my original stock. Torqueing the action screws to the 20"lbs. like my original stock had my favorite RWS Subs shooting 1" groups at 50yds. instead of the less than 1/2" groups it was doing. But, the Norma subsonics were under 1/2" and so were the Selliot and Bellier subs. Hhmmmm! There was no action movement in the 2nd stock using 20"lbs. so I started experimenting. At 35"lbs. there was action movement so I backed off to 30"lbs on both screws. That was the answer. Now the RWS subs are back to itty bitty groups and the Norma subs grouping has expanded. So interesting how different torque settings can make such a difference. Next I'll get it pillared with aluminum pillars then bedded. That should help out all of the different rounds I like to use.
