Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for .224 Weatherby Magnum, 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.

Drives 55-grain bullets past 3,850 fps, significantly faster than the .22-250 but requiring the larger Weatherby Mark V action and the proprietary head diameter that comes with it. SAAMI-standardized and still factory-loaded by Weatherby.
