I don't like the bands to be tight on any 336 except to be tight enough to stay on the mag tube but a bit loose on the barrel.
So i open up the band where it fits on the barrel to be a slip fit when tightened down.
The band on the stock I like it snug on the wood but a slip fit on the barrel, which means I also have to sand that part of the clamp out a bit.
Make sure the barrel and the end of the mag tube are not putting any pressure on each other. They should be separated by the barrel band.
If not the magazine tube is not coming out of the forearm straight and needs adjustment there to make sure it's straight with the barrel
all the way to the end.
