Winchester 22 WMR 40 gr JHP PDX1 22 Defender 50/Box

Rimfire is the most popular ammunition in the world – and it’s the ammunition most of us loaded up with when we first began shooting.

Rimfire has come a long way from the simple “lead roundnose” cartriges that use to rattle around in our pockets. Today, Winchester leads the industry in developing and delivering a modern rimfire ammunition. These jacketed hollow points are precise, constructed of the highest-quality components, optimized for reliability and superior performance.
