According to the Hodgdon Powder Co. reloading web site, the "Trim to" length is 2.090 inches and the COL is 2.860.
Obviously "trim to" length is not the max cartridge length, but its better than no information at all.
If we use the .308 as a guide, Trim to is 2.005, and the max case length is 2.015. This would make the .300 WSM max length somewhere in the vicinity of 2.100 inches, but you certainly would want to check yourself.
