Magazine Follower - "Short" Magnum for .264, .300 Win Mag, .338 Win Mag, etc.
The Magnum follower (not H&H). It is used with what Winchester used to call the "short magnum cartridge" rifles (.264 Win Mag, .300 win Mag, .338 Win Mag, etc. - not to be confused with today's "WSM" and "WSSM" cartridges. This is an original Winchester part in excellent condition.
The pre-war followers have the top-side relief cut. Post-war followers do not have this feature.
