• Industry leader in producing reliable, clean-burning primers for reloaders and ammunition manufacturers.

---

✅ Primer Classification:

---

✅ Primary Purpose:

CCI 450 primers are specifically designed for:

• Magnum small rifle loads

• High-pressure cartridges

• Ball powders and hard-to-ignite propellants

• Cold weather shooting

• Semi-auto and gas-operated rifles that benefit from a harder primer cup

---

✅ Best Applications & Compatible Cartridges:

⚠️ Not recommended for low-pressure loads or light target loads where a standard small rifle primer (e.g., CCI 400) may suffice.

---

✅ Key Features of CCI No. 450:

🔹 Magnum Ignition Power

• Produces a hotter and more sustained flame than standard small rifle primers

• Ideal for ignition of dense ball powders like H335, BL-C(2), W748, etc.

🔹 Thicker Primer Cup

• Resists piercing and deformation in high-pressure loads

• Better suited for semi-automatic rifles like AR-15, AR-10 where free-floating firing pins may cause slamfires with softer primers

🔹 Reliable in Cold Conditions

• Maintains consistent ignition when temperatures drop

• Essential for hunters or tactical shooters in adverse weather

🔹 Non-Corrosive and Non-Mercuric

• Will not harm barrels or components with long-term storage

🔹 Clean-Burning Formula

• Helps reduce fouling

• Aids consistent powder ignition in long shooting sessions

✅ Reloading and Safety Notes:

1. DO NOT substitute CCI 450 for CCI 400 (or vice versa) without working up the load. The increased energy of the 450 can raise chamber pressures.

2. Pay attention to pressure signs:

   • Flattened primers

   • Sticky bolt lift

   • Ejector marks

3. Follow Published Load Data:

   • Use data from sources that specify CCI 450 or other magnum small rifle primers

4. Excellent for AR-type rifles:

   • The harder cup resists slamfires

   • Especially important for free-floating firing pin systems (e.g., AR-15, M16, Mini-14)

5. Ensure Proper Primer Seating:

   • Fully seated below flush

   • Clean primer pockets aid uniform ignition

---

✅ Powder Compatibility:

Best suited for:

• Ball powders like H335, BL-C(2), Win 748

• Double-base powders with harder ignition characteristics

• Slow-burning powders in small cases

Works well in load development for:

• High-pressure .223/5.56 loads

• High-performance 6.5 Grendel or 6mm ARC in AR platforms

---

✅ Packaging Options:

• 100-count trays

• 1,000-count bricks (10 trays of 100)

• 5,000-count cases (bulk case for large-volume reloaders)

---

✅ Why Choose CCI No. 450?

✅ Built for magnum loads where standard small rifle primers fall short
✅ Hard cup construction protects against slamfires and primer flow
✅ Superior performance in extreme conditions
✅ Ideal for semi-auto, high-pressure, or ball powder loads
✅ Manufactured to tight tolerances for consistent performance shot-to-shot

---

⚠️ Not Ideal For:

• Light .223 loads using extruded powders (Varget, IMR 4198)

• Bolt-action rifles shooting subsonic or target ammo

• Applications requiring soft cup primers for light firing pin strikes
