Remington .22 Win Mag 40gr JHP 50 Rounds | 1910 FPS Varmint Ammo R22M1

The Remington .22 WMR 40-grain JHP is built for the hunter who needs "centerfire attitude" in a rimfire platform. A major frustration with rimfire ammo is inconsistent velocity, which leads to unpredictable misses just when the shot matters most. Remington has solved this by tightening tolerances on their primer mixes and brass casings. The result is a cartridge that ignites reliably and delivers the shot-to-shot consistency required for precision varmint control and small game hunting.

The real benefit here is a predictable, flat trajectory. By locking in a muzzle velocity of 1,910 FPS, this load eliminates the vertical "stringing" that plagues cheaper rounds. The 40-grain Jacketed Hollow Point is the perfect middle ground: it’s heavy enough to maintain momentum but designed to expand explosively on impact. This ensures deep enough penetration followed by a massive energy dump, which is exactly what you need for a clean, ethical dispatch at extended rimfire ranges.

Pushing 324 ft-lbs of muzzle energy, this round packs a serious punch while remaining incredibly easy to shoot. The high-quality brass creates a perfect seal in the chamber, ensuring every bit of pressure is used to drive the bullet accurately. With a flat arc that lets you stay "dead-on" out to 100 yards with minimal adjustment, it’s a reliable powerhouse for clearing pests or filling the small-game vest. It turns your magnum rimfire into a truly surgical tool in the field.
