I have a Rem 700 that sits in a McMillan Hunter's Edge stock that I'm interested in putting a new barrel on. What are people's thoughts on a Bartlein 30 cal 10 twist SS #3 fitting the stock inlet channel? The McM website says "The slender forend will accept up to a factory magnum barrel contour or custom barrel similar to a #3 Douglas or smaller." The Douglas #3 contour has a muzzle diameter of 0.625 where as my barrel in it now has a 0.660. The Bartlein has a 0.670 diameter. What I'm worried about is the diameter of the contour that goes through the inlet of the stock. Does the Bartlein have a totally different contour than the factory Remington? Should I be concerned? Also what does my existing barrel weigh? Just the barrel? Thoughts?
