This video provides a comprehensive velocity test of various .22 WMR (22 Magnum) ammunition types fired from a Rossi RS22M rifle. The instructor, Buckeye Ballistics, meticulously records chronograph data, including average velocity, standard deviation, extreme spread, and foot-pounds of energy for each round. The test highlights differences in performance between handgun-focused rounds and rifle rounds, and addresses common misconceptions about semi-automatic rifle velocity loss. The instructor also discusses the challenges of conducting outdoor tests due to weather and equipment issues, demonstrating resourcefulness with lighting solutions for the chronograph.
This ballistic gel test compares Winchester Super X 40gr .22WMR and Winchester Dyna Point 45gr .22WMR. The Super X exhibited better expansion and higher retained velocity, while the Dyna Point showed a flatter mushrooming effect and 100% weight retention. The test also noted the impact of ballistic gelatin calibration on penetration depth.
