Benchmark will make pretty much anything you want in stainless. Cut or buttoned. Cut twist rates can be whatever you want as it's all done on CNC. Custom contours are easy too, but there is a charge.
I ordered a cut stainless 7mm 1-8 last week. Winchester featherweight that tapers to .600" at 24" finished.
8 month lead currently.
That’s just about what my Mashburn barrel is. Originally a Bart #2 but it’s been milled on pretty heavily.
