Federal Large Pistol Magnum Primers #155

Looking for Federal primers magnum built for heavier pistol loads? The #155 is the same large pistol magnum primer Federal uses in their own high-quality ammunition, made to exacting standards for dependable, consistent ignition. When a load calls for a slower-burning powder that a standard large pistol primer can’t reliably ignite, this magnum version delivers the extra flame needed for full, uniform combustion.

Federal’s manufacturing process is built around tight tolerances and rigorous testing, which is exactly what magnum handgun cartridges demand — inconsistent ignition on a heavy magnum load isn’t just a performance issue, it’s a safety one. As always, cross-reference your specific magnum load with Federal’s official reloading data before loading.

If your cartridge doesn’t specifically call for the extra magnum energy, our standard Federal Large Pistol Primers #150 is the more economical, everyday choice.
