Nope, the tip bedding I discussed is of the forend itself. Mostly it keeps the tip from wobbling back and forth, which is apparently what causes some problems.
JB, I believe you hit the proverbial nail squarely on the proverbial head. IME, many rifles (of any type) that have forend/barrel contact also have this "wobble" problem. Also IME, simply eliminating the wobble makes a ton of difference in group size. Often this can be accomplished by simply filing a shallow, narrow groove in the bottom center of the forend tip with a rattail file. This results in the barrel being "cradled" between two high spots where it cannot wobble.
