[QUOTE="Fitch, post: 421198, member: 19372"] The advantage of free floating the barrel is that it starts the dynamics of being fired from the same initial conditions for each shot. It's a cantilevered beam with very repeatable and predictable dynamic behavior. If you touch the floated barrel anyplace except very close to the receiver barrel junction, it changes things from simple and predictable to complex and chaotic. The barrel doesn't stay straight and wag up and down, it recoils with several different modes of vibration which means it will hit the full length bedding in different places bouncing off it and deflecting the muzzle slightly (it doesn't take much) in unpredictable directions. With barrel expansion due to heat, stock dimensional changes due to heat or moisture, the fit of the barrel in the channel may be different for each shot which means it starts the dynamic process from different initial conditions. That is why free floating is much better than full length bedding. That's why free floating and glass + dual pillar bedding has almost completely replaced full length bedding which used to be all the rage 3 or 4 decades ago. Fitch [/QUOTE]
