In terms of making an action more "stiff" which would be the better choice? I understand the idea of the integral recoil lug on the Nightforce to alleviate some of the force against the base screws. However, that comes with the cost of elongated holes that would not provide any mechanical advantage against the flex of the action. On the other hand Murphy Precision (or similar) has an 8-40 screw instead of the 6-48. The new holes would be machined to precisely match the bases holes and provide an actual mechanical advantage against the flex of the action. Are the 8-40 screws big enough to handle this stress on a Rem 700 chambered in 338 Norma Mag?
