CCI Large Pistol Primers #300

Looking for CCI Large Pistol Primers? The #300 is a reliable, all-purpose large pistol primer trusted by reloaders for consistent, sensitive ignition across a wide range of standard-pressure handgun cartridges. CCI primers are continuously tested and improved, and today’s formulations are more sensitive, easier to seat, and more compatible with progressive and automated loading equipment than ever before.

Each #300 primer uses a modern, non-corrosive and non-mercuric initiator mix, delivering a clean burn that keeps primer pockets cleaner and equipment running smoother between reloading sessions — a real advantage for high-volume shooters loading multiple calibers. It’s a proven, dependable match for cartridges like .45 ACP, .44 Special, .45 Colt, and .10mm Auto, making it one of the most versatile primers in a reloader’s bench inventory. As always, cross-reference your specific load with CCI’s official reloading data before loading.

If your load calls for extra ignition power in a heavier magnum handgun cartridge, our CCI Large Pistol Magnum Primers #350 is purpose-built for that step up in performance.
