I have two Marlin 336SC, .32 Winchester Special Lever Guns. One with microgroove rifling, and one with ballard. I would not part with either! I reload my own ammo for these. RCBS has the dies still in production. Both Hornady, and Speer make a 170 grain bullet for the .32 Winchester Special. Also I see ammo available for the .32 W.S. at gun shops. Marlin discontinued the .32 W.S. chambering in the 336 line, in 1963.
