Even on the 98 Mauser, I prefer to float the whole barrel because there is enogh receiver ahead of the lug for support. On a Sako or Howa, on the other hand,I'll bed a short section of barrel because the lug is at the extreme front of the receiver. I like to clear the bottom of the lug on virtually everything and the bottom, front, and sides on a Remington. For at time, I bedded the sides of the lug on Remingtons in the belief that it would prevent twisting of the round receiver in the bed from torque. I really can't say that it did any good. Since clearing everything but the back of the lug had worked so well, I reverted back to that technique and have been happy about the choice. GD
