RE: Remington 700 Issues .300 WSM
300WSM in a Remington.... well there's your problem..... hehehe
For real though, we have to date, sent 23 Remington 700's back for the exact same issue.
Reasons vary according to who you speak with at Remington..... from tooling marks, burrs, ect in the chamber to headspace deficiencies to bolt and extractor problems.
The Big Green aint what it used to be... by no means!
