Winchester Small Pistol Magnum Primers #1-1/2M
These non-corrosive all-weather primers provide a reliable ignition that is both quick and consistent, regardless of the shooting conditions. Primers are subjected to consistency and sensitivity testing at temperatures and under situations that are much outside the range of typical use. These tests are performed continuously and with great care.
Winchester guarantees improved sensitivity for more positive firing in all types of firearms, carefully controlled weights of primer mixtures, consistency in size and quality, precise measurements and tolerances for anvil heights, and durability in a wide range of temperature and humidity extremes. Winchester also provides a lifetime warranty on all of its products.
