Hey guys I’m new to this forum and I’m looking for a little guidance. I recently purchased a new 24” carbon fiber proof research barrel in 308 cal however, its uncut and will need to be milled to fit an action. Can I have a gunsmith chamber it for 300 wsm even though the barrel is marked 308? I own a Defiance GA hunter short action and was going to use this for the build. Any incite on this would be greatly appreciated.

The bore size is .308. Yes it will work for a 300 wsm, or. 300 wm etc, as they all share the same bore size.
