This is not an exact answer to your question but has to do with the action screws and their tightness. LA/SSS trigger in a B&C Carblite stock (no pillars). I installed a front pillar and bedded the action and recoil lug with JB Weld. I tighten the front action screw very tight, it is metal to metal so I do not think the actual torque is all that important, just real tight. The back screw area is bedded with JB Weld. If I tighten the back screw too much the sear will not inguage. Loosen it 1/8 -1/4 turn and every thing works fine......however the tightness of the rear screw is critical to accuracy. The tang is floated. I believe I am crushing the stock at the rear screw and that is torquing the action out of shape.
My conclusion: You must use pillers both front and rear and make very sure you have a metal to metal fit and have not torqued the action out of shape. I still do not believe it is necessary to use a torque wrench....just real tight. If accuracy falls off the first thing I check is the screw tightness. I bed the lug very tight and have never used your method of making sure it is seated.......that is not a bad idea.
