I would contact Marc Sheehan sheehan93@hotmail.com
He is Don Bowers protege'. Don Bower and his brother John were the early pioneers of LR shooting with Contenders.
They did things accuracy wise from the bench that most people couldn't imagine with 14" Contenders. John is now dead but Don is alive but his health is now failing and is ability to remember-fading.
Marc could give you several options. Pillar bedding your own stock or having someone do it for you would be the ideal in my opinion, but washers used properly can get great results.
