The Winchester Repeating Arms Company was founded by Oliver Winchester in 1866 with the design of the Winchester Model 66. Eight years later, operations were expanded to include ammunition production. In the nearly 150 years since, Winchester has successfully sustained its legacy of American tradition, building a name that has become synonymous with qualities that exist in only the finest of businesses. Their commitment to excellence, outstanding pride in their product and innovative spirit has cemented their place at the head of the arms and ammunition industries.

For many, Winchester means fine weaponry. For most, it means ammunition. As a major global supplier of high-quality ammunition, Winchester has long held a reputation for its second-to-none research and development practices as well as their aforementioned innovative spirit, which has yielded some of the world's most popular firearms cartridges. It is also responsible for their inventive lines of ammunition, including the unmatched "Ballistic Silvertip" line of rifle ammunition.

As noted, each box of Winchester X22MHLF .22 WMR ammunition is a product from Winchester's "Varmint LF" line. Marketed as a hunting load for vermin and predators, all Winchester Varmint LF ammunition features lead-free bullet technologies alongside the time-tested loads characteristic of one of America's oldest ammunition manufacturers. This state-of-the-art load, like all Winchester ammunition, is manufactured in the United States by the Olin Corporation at the Winchester Centerfire Operations Facility in Oxford, Mississippi. Additionally, all ammunition lots are inspected for quality assurance purposes prior to packaging.

The cartridges found in each box of Winchester X22MHLF .22 WMR ammunition begin with a lead-free jacketed hollow point projectile. This unique projectile boasts incredible terminal ballistics for a cartridge of its size. Additionally, the jacket is bonded to a tin core to ensure that there is no vaporization of lead and shooting remains safe. Despite being a jacketed hollow point, this cartridge is also known for its superb flight characteristics and superior muzzle velocities.

Every box of Winchester X22MHLF .22 WMR ammunition contains 20 non-corrosive, brass-cased cartridges. Each cartridge is loaded with the aforementioned 28 gr lead-free jacketed hollow point projectile, which provides for both superior terminal ballistics and increased muzzle velocities. In fact, this particular load is capable of producing muzzle velocities that have been observed to travel at speeds of up to 2,200 fps.
