I put a laminated stock on a Vanguard 300 Wby Mag. Had the action glass bedded and floated the barrel. I am getting about 1 1/2 groups. They were a little better with the plastic stock but not a whole lot. As a whole do Vanguards need pressure on the barrel? What about these Limbsaver Things that go on the barrel to reduce vibrations, anybody ever use one? Do they work?
