The .40-65 Winchester cartridge was introduced in 1887 for the Winchester Model 1886 lever-action rifle and later chambered in the Winchester High Wall single-shot and Marlin Model 1895 lever rifle. Originally developed as a black powder cartridge, it gained popularity among hunters and target shooters for its balance of power and accuracy.

By the early 1900s, the .40-65 WCF (Winchester Center Fire) transitioned toward smokeless powder loads, remaining in Winchester’s catalog until around 1935. Today, it remains a favorite among black powder cartridge rifle (BPCR) enthusiasts and handloaders who enjoy cartridge reloading for vintage rifles.

Modern .40-65 Winchester reloading combines traditional bullet casting and black powder or reduced smokeless loads, offering excellent performance in replica lever-action rifles and single-shot competition guns.

Starline suggest forming 40-65 cases from .45-70 brass if fire formed case length must be longer than 2.090 inches.
