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.

Quick Summary

This .22 WMR velocity test utilized a Rossi RS22M rifle to chrono various 22 Magnum loads. The instructor recorded average velocity, standard deviation, extreme spread, and energy for each round, noting that 30-grain bullets generally achieved the highest speeds, and that semi-automatic rifle velocity loss is negligible.

Frequently Asked Questions

What rifle was used for the .22 WMR velocity test?

The .22 WMR velocity test was conducted using a Rossi RS22M semi-automatic rifle, which features a 21-inch barrel. The instructor chose this rifle for its reliability and noted that the velocity difference between semi-automatic and bolt-action rifles is negligible.

Which .22 WMR ammunition types were tested for velocity?

The test included a wide range of .22 WMR ammunition, such as Winchester Silver Tip, Speer Gold Dot, Federal Punch, Hornady Critical Defense, CCI Maxi Mag, Winchester Dyna Point, Arms Core, CCI Game Point, Remington Premiere, CCI VNT, Hornady V-Max, CCI TNT, Federal Spear TNT, and Winchester HV Varmint loads, in various grain weights.

What factors can affect chronograph readings during outdoor testing?

Outdoor testing can be affected by weather, particularly rain, which can cause errors on chronograph sensors. Additionally, powder residue or debris flying over the sensors can interfere with readings. Using integrated lighting on the chronograph can help in low-light conditions.

Are handgun-focused .22 WMR rounds different from rifle rounds?

Yes, handgun-focused .22 WMR rounds are designed for shorter barrels and generally produce lower velocities when fired from a rifle. The test included these rounds to compare their performance in a rifle platform against dedicated rifle ammunition.

What are the fastest .22 WMR rounds tested in this video?

The 30-grain .22 WMR rounds generally yielded the highest velocities in this test. Ammunition like CCI VNT, Hornady V-Max, CCI Maxi Mag TNT, and Federal Spear TNT were advertised at 2200 ft/s, with some Winchester loads advertised even higher at 2250 ft/s.
