I've got a Remington 700 that I would like to upgrade the stock on. It has a pencil barrel with about 2000 rounds of .30-06 through it and I'm thinking it may still have enough life in it that I don't want to replace it just yet.

In the mean time, I'd like to put it into a Manners mini chassis and stock, or put it into an AICS long action stock. Since I will want to replace the barrel with a varmint, bull, or M-40 contour, would it be a good idea to buy a stock channeled for the heavier contour and allow the pencil barrel to be "extra" free floated? How will this most likely impact precision? Should I just wait until it's time to re-barrel?
