[QUOTE="Fiftydriver, post: 105676, member: 10"] D-A, The depth of the mounting hole into the barrel will depend on several things, barrel diameter and chamber diameter mainly. As a general rule, I mill them to 0.200" deep and use a bottom tap to thread right to the bottom of the hole. I also use a flat bottom bolt to utilize as much thread contact as possible in this depth of hole. If the Barrel Bedding V-Block, at least my design, is set up correctly, there is no need for high grade mounting bolts. Now you certainly want quality bolts but nothing special is needed here. The reason is because the mounting bolts serve only one purpose, to hold the barrel "DOWN" into the V-Block. They in no way have to control the recoil forces. This is accomplished by the conventional recoil lug in its conventional location. Most clamp on blocks use the block itself for the recoil lug and also rely on frictional clamping pressure around the barrel to transfer recoil energy. This system works well but requires a large clamping area and this also effects scope mounting height and appearance of the rifle, my system does not. The mounting screws are centered in the ports and also have 82 degree tapered heads that mate with the 82 degree tapered ports to perfectly align them in the mounting holes. When done correctly, they should be totally floated and only touching at the barrel threads and at the 82 degree tapered head of the bolt to Block. There are no recoil stresses at all on these bolts, no more then a conventional bedding system. Good Shooting!! Kirby Allen(50) [/QUOTE]
