History of 32 Long Cartridge:
Introduced in 1875 as a black powder cartridge for the new line of Colt revolvers, it originally had a .313 inch diameter outside-lubricated projectile, which was later changed to inside lubrication, leading to a diameter change to .299 inch projectile. Colt was the only pistol company to chamber this caliber.
