CCI 0016 Large Pistol Magnum Primers No. 350 - 1000 Count Box

The CCI 0016 Magnum Large Pistol Primers deliver consistent ignition for high-pressure magnum cartridges and heavy powder charges. These No. 350 primers provide the extra heat and duration needed for reliable ignition in demanding handgun applications.

What Makes This Different

Magnum primers contain approximately 14% more priming compound than standard primers, generating higher flame temperatures and extended burn duration. This extra ignition power ensures complete powder burn in magnum cartridges like .357 Magnum, .41 Magnum, and .44 Magnum. The enhanced sensitivity design maintains consistent performance across temperature extremes where standard primers may fail.

Key Features

• Extra-hot priming compound for magnum cartridge ignition
• Large pistol primer size fits .357 Mag, .41 Mag, .44 Mag, and similar cases
• Non-corrosive and non-mercuric composition prevents barrel damage
• Lead-free construction meets environmental regulations
• Consistent cup thickness ensures uniform seating depth
• Factory-sealed packaging maintains primer integrity during storage
• 1000-count bulk box reduces per-round cost for high-volume reloaders

These primers excel in competition shooting where consistent velocities matter, hunting applications requiring maximum powder burn efficiency, and self-defense loads demanding absolute reliability. The magnum formulation compensates for slower-burning powders and dense charge weights that challenge standard primers. Temperature stability ranges from -20°F to 150°F without significant performance degradation.
