Yeah, I've got a KS Arms 7mm 8" twist 5R tube in the safe waiting to go on a 7WSM Montana. It's a contour dupe to the end of the fore-end, and then tapers to 0.600" at 24". Should improve balance a bit, with a slight muzzle bias more to my liking. But this is a utility killing rifle, at 7.5lbs with scope, not an "ultimate lightweight". My 7-08 Montana at 6.5 lbs scoped fills that role for me, and goes sheep hunting whenever I do.
Jeff's question of the ultimate scope for the ultimate lightweight rifle is an interesting one. While some here tend more toward a slightly heavier rifle in the name of reliability, I do the same with scopes. My Kimber setups could easily each drop 0.5+lbs if I were to go back to Talleys and Leups, but I've had far more failures in the field with scopes than rifles, so I tend to cut weight on my rifles and add it to my scopes. Instead of M70's with Leups, I end up with Montanas and SWFA SS's.
