Hi gents I’m looking for a little guidance. I’ve had my savage 111 in 300 win mag for awhile and I want to put a new barrel on it. The barrel I had in mind was a Krieger Match #17 heavy varmint with a 1-10 twist. I was wonder if I would need a new shank because the barrel diameter is larger than the factory barrel. I’m trying to make a long range target and a hunting rifle. Any guidance will be great about the shank and sizes.
