The Aguila 22 Winchester Auto ammunition is purpose-built for shooters who appreciate the classic .22 WinAuto cartridge and the rifles it was designed for. This 45-grain lead round nose load delivers the accuracy and reliability you need for target work and small game hunting, with a muzzle velocity of 1030 feet per second that keeps things smooth and controllable through the action. Whether you're shooting a Winchester Model 1903 or another rifle chambered in this cartridge, this is ammunition engineered to cycle consistently and group tight downrange.
Lead round nose bullets have earned their reputation for reliable feeding and straight-line flight. At 45 grains, this projectile strikes a practical balance for plinking, accuracy drills, and harvesting small game at typical hunting distances. The modest muzzle energy of 106 foot-pounds is appropriate for the cartridge's intended use, and velocity is stable enough to maintain point-of-impact across reasonable shooting distances—you'll still have 892 feet per second and 80 foot-pounds at 100 yards.
Aguila has packaged this load in bulk-friendly cases of 5000 rounds (50 rounds per box), so serious shooters and regular range-goers can stock up without constant reorders. If you shoot .22 WinAuto regularly, having a reliable supply on hand makes sense.
