[QUOTE="J E Custom, post: 418767, member: 2736"] To check if there is flexing when tightening the action screws place a magnetic dial indicator base like in Roys picture on the front reciever ring and the dial on the rear ring/surface and as you tighten the action screws is there if any change in the indicator there is some flex in the action (Not good) and skim bedding or re bedding will be nessary for the best accuracy potential. If a pillar bed is done right with the right materials it should not have any stresses in it. I use to use bedding screws to pull the action down into the stock and was allways in fear of applying undo stress to the action and flexing it(Even though they are very strong they can be flexed ) pulling the action out of true even if only a few thousandths. I now use spring clamps(Surgical tubing would also work) to force the action down it to the bedding with a little help from my self. they will supply enough force but not to much. I also bed about 1/2" to 3/4" in front of the recoil lug on long barreled rifles to balance the footprint and if it doesn't work/shoot well I can remove it without disturbing the bedding later. After the bedding has cured well and is cleaned up I install the action screws and start with 35 inch pounds of torque. At the range I will increase it to see if the zero changes.(It should not if the bedding is right) but there is a sweet spot for torque that should be found and noted in the load records. Again; The action should not have stress if the bedding is done right. If it does it can be skim bedded and not tightened up to fix this. (A good place to use the surgical tubing). There are other ways to do a stress free bedding job and this is just what works for me. J E CUSTOM [/QUOTE]
