Free floating is the EASY way with most stocks. In a VERY highend stock, i prefer a full length bedding job. All of mine but two are free floating. Two of those have some bedding work. Then i have 2 with full length bedding and they are a tad more accurate.

The high end stocks with full length aluminum bedding blocks for the action do float the barrel but the block extends into the forearm sides to make the entire stock more rigid...such as a B&C Medalist stock.

IMO a lot depends on application and potential weather conditions that can effect some type of stock materials more than others.
