Rimfire ammunition has been a staple in the shooting world for over a century. Known for its affordability, versatility, and ease of use, rimfire ammo is a popular choice among shooters of all levels.

Understanding Rimfire Ammo

Rimfire ammunition gets its name from the firing mechanism it utilizes.

This design allows for simpler and more cost-effective manufacturing, making rimfire ammo an affordable option for shooters.

.22 Long Rifle (LR): The .22 LR is the most common and widely used rimfire caliber. It is versatile, affordable, and suitable for a wide range of shooting activities, including plinking, target shooting, and small game hunting.

.17 HMR: The .17 Hornady Magnum Rimfire (HMR) offers higher velocity and flatter trajectory compared to the .22 LR. It is popular for varmint hunting and precision target shooting.

.22 WMR: The .22 Winchester Magnum Rimfire (WMR) is a step up from the .22 LR in terms of power and range. It is commonly used for varmint hunting and offers improved accuracy and terminal performance.

.17 Mach 2: The .17 Mach 2 is a necked-down version of the .22 LR, designed for increased velocity and accuracy. It is primarily used for target shooting and small game hunting.
