[QUOTE="Bart B, post: 501052, member: 5302"] Here's two pictures of a machine rest with one of David Tubb's model 2000 barreled actions clamped in. Conventional rifles clamp in the same way except their butt stock has escutcheons on each side in front of the butt pad where ball tipped cross bolts hold it. There's adjustments for windage and elevation. Designed in the late 1950's, about a dozen or more were built for high power rifle competitors to use test rifles and ammo. They weigh about 70 to 80 pounds. The upper part, or cradle, recoils back about 2 inches with a 13-pound .308 Win. rifle clamped in. Its 3-point suspension of 2 V blocks and one rod sliding on another allows repeatability when pushed back into battery after each shot of about 1/100th MOA. Old Winchester Model 70's rebuilt into match rifles have produced 10-shot groups at 600 yards under 1.5 inches from this monster.
