In the endless pursuit to save money while still enjoying a long, fruitful day at the rifle or target range, shooting enthusiasts and plinkers still turn to the storied rimfire ammo for an inexpensive way to enjoy their small caliber firearms. In contrast to centerfire cartridges that are triggered by primers positioned in the center, rimfire bullets are ignited by a rimfire primer when the firing pin strikes the rim of a cartridge. Although once utilized in many calibers throughout history, this illustrious and easy to manufacture technology now primarily survives in 22 rimfire ammo. The primary advantage to you the shooter is that the cost of a box of rimfire cartridges is far more reasonable than a box of centerfire cartridges. When you shop for rimfire cartridges at exceptional Webyshops prices, you'll save drastically more on ammo for your next outing, and be sure to add several boxes to your cart to save on delivery with free ground shipping.
