In general, most rifles that are properly bedded shoot best when the barrel is free-floated. It is important to understand that barrels vibrate when a shot is fired. Ballisticians refer to these vibrations as a barrel’s “harmonics.” Anything touching a barrel at the time of firing, such as a warped fore-end, will affect these vibrations. This in turn affects the gun’s ability to place its shots consistently. To put it in other words, it affects the gun’s accuracy potential. Free floating a barrel is simply an attempt to eliminate a potential source
of accuracy troubles. In most factory rifles, free floating will help accuracy, especially if it is done in conjunction with a good bedding job.
