Small Pistol Magnum Primers

Small pistol magnum primers are a must-have for reloaders of many handgun cartridges with "Magnum" in the name such as the .357 Magnum. They are stronger than normal primers in order to withstand the greater forces involved in firing a magnum load.

SPM primers measure .175" (4.45mm) in diameter and are used not only for the aforementioned magnum cartridge but also for slower-burning powders.

Remington, CCI, and Federal are just a few of the names involved in producing quality small pistol magnum primers for sale - many of which, you'll find in-stock here at Widener's.
