My gunsmith hunting pard built me one on a Kimber 8400 WSM that Tanner had beat the crap out of. Thought I had a Rock Creek #2 barrel but it ended up 0.575” at the muzzle so I think it was their mountain contour. Shoots great, mag box is a hair over 3” so no worries with OAL. I’m gonna have him cut it back to somewhere between 18-20” so I can use the Ultra 7.
