History
Part of Winchester's big-bore black powder lineup for the Model 1886 lever-action and Model 1885 single-shot rifles, the .50-100 occupied the middle ground between the .50-90 and .50-110. Like its siblings it is a black powder cartridge capable of taking the largest North American game at moderate ranges.
