The .32-40 Ballard (also called .32-40 Winchester) [Barnes, Frank C., ed. by John T. Amber. "Cartridges of the World" (Northfield, IL: DBI Books, 1972), p.67.] is an American rifle cartridge.

Introduced in 1884, the .32-40 was developed as a black powder match-grade round for the Ballard single-shot Union Hill No. 8 and 9 rtarget rifles. Using a 165 grain bullet over convert|40|gr|g of FFg (muzzle velocity convert|1440|ft/s|m/s|abbr=on, muzzle energy 755 pd-ft), the factory load gained a reputation for fine accuracy, with a midrange trajectory of convert|11|in|cm at 200 yards (180 m). [Barnes, p.47.] It was available in Winchester and Marlin lever rifles beginning in 1886. [Barnes, p.47.] It stopped being a factory chambering around 1940. [Barnes, p.47.]

It provides performance sufficient for deer at up to 300 yards (270 m) in a modern rifle, for which it can be loaded to about equal the .30-30. [Barnes, p.47.] It is more than enough for varmints, including coyotes and wolves, or medium-sized game.

High-velocity loads (such as the convert|1740|ft/s|m/s|abbr=on example) should not be used in the old Ballard or Stevens 44 rifles.

The .32-40 also served as the basis for Harry Pope's wildcat .33-40.
