SAMMI specs for the 6.8W are 2.755 min - 2.955 max, both 270 and 300 WSM was like 2.860 and the M7 was chambered in those using a 20" or 22" magnum contour barrels so it should work.
I bought a stripped magnum Model 7 bolt off CDDN, picking up the Lawton Magnum extractor kit, the stealth bottom...
Here is my M7 current config, I'd like to know
Nice work Teflonhunter, this is my current configuration, looking to ditch this factory setup, and the .308 barrel to build a 6.5 PRC on this action, purchased the magnum bolt already, can you tell me how hard it was to make the M700 stock work...
