From Cartridges of the World, 4th Edition --



For the Winchester Model 1886, the largest cartridge was the .50 caliber. There were two variations of it, the .50 Express (aka .50-110-300) and the .50-100-450. While these were different loadings in the same case, the rifles were different with different rates of twist.
