[QUOTE="Bart B, post: 895210, member: 5302"] Barrel blocks clamping barrels have been used epoxied in fore ends of NRA high power match rifles with great success. They're sort of a shoulder-fired rail gun design. But bedding anywhere under the barrel in front of the receiver's never been popular in such rifles. Too many good tests have proved that starting out with a cold barrel, pads under the chamber area cause shots to string up as the barrel heats and expands changing the pressure under the barrel in that area. Besided, that pad transfers fore end bending from different shooting positions (they all do to some microscopic amount). 30" heavy barrels (straight taper 1.2" to 1.0") have been fit to match winning and record setting Win. 70 rifles totally free floating for decades. As a Rem 700 receivers are about 1/3rd as stiff as a Win 70 one, they will bend more for any weight barrel screwed into it. But the amount of bending will be repeatable so it may not be an issue.
