Cantilever . . .
The barrel of any free-floated rifel is supported by cantilever from the receiver. Not the best for a long barrel (>21" or so).
All serious modern competition guns are this way, so that the sling pressure does not effect the barrel and POI.
Many guns are glass bedded or bedded other ways and are more than accurate enough for hunting or other uses. Bench rest rifles are often bedded, since the pressure on the stock/barrel is consistent that way.
Muzzle loading rifles often need pressure on the barrel to shoot well, as they are low velocity and barrel harmonics really come into play - thus needing to be controled via bedding. I did some work with mine and went from 4" groups to shooting out the X ring at 50 yards.
