Had a cool old FN Mauser custom 300 Win Mag back in the day with a really nice stick of walnut, it was bedded and floated and began to warp to the side a bit, took it to my 'smith, he milled out a channel in the forend, placed a 6" solid aluminum piece of square bar stock in the channel with epoxy compound, immediately placed the rifle in a vice, used some other attachment to push the forend straight with the barrel, let sit for a couple of days, it was still perfectly straight when I sold it.
