The Winchester 1866 is a lever action .44 Rifle. It allows slugs in tubular magazines of 15.
It has a very distinctive sound and is a popular choice among survivors. The large magazine size and good accuracy and fire rate make it more versatile than the double barreled shotgun, and a great starting weapon.
Though it is classified as a Shotgun, only Slug rounds are available in DayZ, making it handle much like a rifle.
The Winchester fires slightly different slugs which are much more powerful, doing more damage than a Lee-Enfield within the first 50 meters. Damage drops off very quickly - at a mere 50 meters it loses roughly 2,000 damage. This high initial damage makes the Winchester a good choice for close-range fights.
