I Know that others like to use a set screw between the forearm hanger and the barrel to relieve forend to barrel pressure, but I personally like bedding and floating.
I don't like the set screw method, as I want the barrel free of any undue pressure from any source!
I have never had a problem such as you talk about with the #1, even before I began floating/bedding the forend.
However, over the years I have found the consistincy of my hunting rifles to be far more relyable, be they bolt actions or single shots, if the barrel and forend were NOT in contact.
Wood moves, barrels move, and for rifles below the high end and tweeked target rifles, floating and bedding greatly increases consistancy. GREATLY!!!!!!!!!!!
I bed my #1 forends at three points, the front where the forend screw attaches, and one place on each side back close to the action. Then AFTER the forend is solidly bedded, all contacting wood is removed along the sides almost back to the action and below the barrel.
After this is finished and before finishing/sealing the wood, assemble the rifle, rest the forend on a solid surface and while holding the rifle at the grip, make sure the rifle's weight will not bring the wood and barrel into contact.
You want enough clearence to make sure a wet stock will not again bring the barrel/forend into contact.
There are other tricks with the #1, but I have never had a bad one and bedding/floating just decreases the posssibility.
Keep em coming!
