Is it possible to put a muzzle brake on the 116 xp trophy hunter in a 300 win mag? The barrel measures .585 at muzzle so a standard 5/8" 24 pitch (.625") .308 MB won't work? I would have to go with a 1/2" threaded brake, which I only found one for .308. The Bear hunter must be a different contour? Maybe just buy a barrel that's already threaded? Or custom job?
