Getting ready to pillar bed and full action bed a Remington CDL stock for a light varmint barrel, so I thought I would ask the rest of you how you measure the pillars. I will be measuring the pillars after I remove the wood from the inletting, leaving only a small amount on the rear tang area and using some tape on the barrel on the forearm to center the barrel and give me a good center line running the length of the rifle. I check the depth from the bottom of the stock at the trigger guard action screw holes to the bottom of the receiver 4 to 5 times to get a consistent measurement. That will be the measurement for the pillars plus adding 3 to 5 thousandths to insure good metal to metal contact with the trigger guard and the bottom of the receiver. What are your techniques?
