As Im sure a lot of you know; fully floated barrels are not "always" the most accurate. sometimes, it does more good to fully bed a barrel than to float it. I have used silicone < black GE brand> for some time now to help with barrel harmonics on thinner barrels that have issues. The sillicone "dampens" barrel harmonics after a shot, acting just like a silicone bushing on a carbody, or on a motor mount. Ive seen incredible improvements with some rifles.....the best was a rem700 in 308 that had a 22" barrel. Nothing helped until I squirted in the silicone.....then magicly, It started giving sub-moa groups with box and surplus ammo. All your doing is taming the vibrations....think of a tuning fork that is struck, now imagine placing that fork against something as hard as wood. The vibrations are xferred into the wood with great force....now, imagine that same amout of energy resting on a silicone bed.

If you have a weapon that just wont settle down.....try bedding the entire barrel channel in sillicone. If it doesnt work, it will peel right back out....now harm, no foul.
