The Model 1886 was the second firearm John Browning created for Winchester, and it was a game-changer. Until the ’86 was born, many lever-action rifles of the time were limited in cartridge choices and real stopping power for big animals like bison, elk, and grizzlies. With its new and stronger locking-block action, the 1886 was initially chambered for the then-new .45-70 Gov’t, the .45-90 Win. and the .40-82 Win. Other blackpowder cartridges were added to the lineup, including the potent 50-110 Win., and the gun proved strong enough, with a change of barrel steel, to move into the smokeless powder age with the .33 WCF cartridge in 1903.
