[QUOTE="BPreheim, post: 719791, member: 56963"] Where the bolt is hard to lift I would say it is high pressure this could be caused by a chamber or throat out of spec. It could also be caused by interior barrel Finnish or if it has been shot more than you think it could have a section of copper build up that you might not be able to see without a bore scope. The least expensive way to get it fixed will be to send it to Winchester. Have you tried a differant lot of ammo? It could be soft brass. We saw a lot of it when the WSM was first introduced.
