Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for .50-110 Winchester, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

With 110 grains of black powder behind a 300-grain bullet it was capable of taking any North American game and was used for grizzly bear, moose, and bison by hunters who preferred the lever-action repeater to a single-shot Sharps.
