Its full metal jacket and optimal grain weight allow for reduced barrel fouling and enhanced cycling reliability in semi-automatic firearms.

History and Development

Winchester Ammo has a rich history dating back to the late 1800s, known as a pioneer in the ammunition industry.

This historical backbone enables the current iterations, like the WM193K, to benefit from extensive research and technological refinements, resulting in a highly efficient and effective round.
