I have a 26" 7mm barrel contoured in a #5. It is a 1-8 twist. It is a Montana Rifle Man barrel. I bought this barrel to do a rem mag build and use the 180 bergers. But have decided to take the build a little different and need a longer barrel now.
It is a Stainless Steel barrel that has been hand lapped, with a shank at 1.2. The crown end measures .660.
