22 WMR – 45 Gr CPHP – Winchester Dynapoint (USA22M) – 500 Rounds

This 22 WMR load (USA22M) gives small-game hunters a practical rimfire round with more weight than the usual high-speed varmint loads. Winchester loads it with a 45 grain copper-plated hollow point bullet. The copper plating helps the bullet handle cleanly. The hollow point gives it better terminal effect than a plain solid. As a result, this load works well for rabbits, squirrels, pests, and general field use.

Winchester lists this load under its Dynapoint line with a plated hollow point bullet and brass shellcase. Retail listings show 1,550 fps and 240 ft-lbs of muzzle energy, matching the data provided. Therefore, this round gives the 22 WMR platform a useful blend of speed, control, and impact. It does not chase the highest velocity in the caliber. Instead, it uses a heavier 45 grain bullet for steadier performance.

The Dynapoint design keeps the load simple. It expands more readily than FMJ. Meanwhile, it carries more bullet weight than lighter 30 grain options. That makes it a strong choice for small-game hunting where clean hits matter more than raw speed. Moreover, recoil stays minimal. Shooters can stay on target, watch impacts, and make quick corrections.

Each box contains 50 rounds. Each case includes 10 boxes, totaling 500 rounds. That format keeps storage easy and supports regular field use. Winchester uses brass cases with rimfire priming, so this ammunition is not reloadable. Overall, this is a steady, useful 22 WMR load with good small-game utility and clean Winchester rimfire performance. Retailer listings confirm brass casing, 50-round boxes, 1,550 fps velocity, and 240 ft-lbs of muzzle energy.
