Winchester Varmint HE .22 LR ammo delivers the velocity and energy you need for effective small-game and pest control at the rimfire range. Loaded with a 37-grain soft-point bullet designed for expansion, this .22 Long Rifle round is engineered to generate significant terminal energy—the kind that matters when you're taking shots on varmints where quick, clean kills count. Each box contains 50 rounds, and a case holds 20 boxes, making it practical for serious shooters who put in volume at the bench or in the field.

The Varmint HE line focuses on high-energy performance. The segmenting expansion design of the projectile works to create reliable upset on impact, translating that energy into effective shock rather than over-penetration. That balance is what separates purpose-built varmint loads from general-purpose .22 rounds—it's ammunition built with a specific job in mind.

Winchester has been loading ammunition for over a century, and their rimfire offerings reflect that pedigree. Whether you're a prairie dog hunter, a groundhog control specialist, or someone who simply shoots a lot of .22 and wants predictable, hard-hitting performance, Varmint HE ammunition gives you a known quantity and reliable terminal characteristics.
