Product Overview:

CCI #450 is a magnum small rifle primer designed for high-pressure and hard-to-ignite powders commonly used in rifle cartridges. This primer is especially suitable for applications requiring strong ignition, such as with ball/spherical propellants, larger cases, or cold weather shooting.

---

Key Features:

• Magnum Strength Ignition: Hotter flame than standard primers for better ignition of slow or spherical powders.

• Consistent Performance: Engineered for uniformity and minimal deviation shot to shot.

• Reliable in Cold Conditions: Ideal for hunting or shooting in sub-zero temperatures where standard primers may fail.

• Military-Style Sensitivity: Less prone to accidental ignition from rough handling or mechanical impact (compared to more sensitive match primers).

• Use in Reloading: Widely used in reloading cartridges like .223 Remington, 6.5 Grendel, and others requiring small rifle primers.

User Tips:

• If switching from a standard primer to CCI #450, reduce starting powder loads slightly and work up while watching for pressure signs.

• In AR-style rifles, the harder cup can help reduce the risk of slam-fires.

• Excellent choice when reloading for cold environments or using ball powders like Winchester 748 or Hodgdon H335.
