• .44 Magnum

• .454 Casull

• .45 Colt (Ruger/TC only hot loads)

• .445 SuperMag

• .475 Linebaugh

✅ Key Features of CCI No. 350:

🔹 Hot, Magnum-Grade Ignition:

• Produces a hotter and longer-lasting flame to ignite:

  • Large powder charges

  • Slow-burning handgun powders like H110, W296, Accurate No. 9, 2400

  • Compressed loads or ball powders that are harder to ignite

🔹 Strong Primer Cup:

• Built to handle high-pressure handgun loads

• Reduces risk of primer flattening, blowouts, or primer flow under magnum recoil

🔹 Non-Corrosive & Non-Mercuric:

• Clean ignition

• Safe for both firearms and long-term ammo storage

🔹 Clean-Burning Compound:

• Designed to reduce fouling

• Improves reliability during long shooting sessions, especially in revolvers

✅ Reloading Tips:

1. Match Your Data

   • Always use published reloading data that specifically calls for magnum primers

   • Substituting standard for magnum (or vice versa) without data can change pressures significantly

2. Watch Pressure Signs

   • Check for flattened primers, sticky extraction, or excessive recoil

   • If seen, reduce powder charge and rework the load

3. Primer Seating

   • Seat primers fully and consistently below flush

   • Clean primer pockets for uniform ignition

4. Crimping

   • Magnum revolver cartridges often benefit from a firm roll crimp to enhance powder burn

5. Temperature Sensitivity

   • CCI 350 primers are known for consistent performance even in cold weather—a bonus for hunters

---

✅ Not for Use In:

• .45 ACP or .44 Special standard-pressure loads
  (Use CCI 300 or equivalent standard large pistol primer instead)

• Rimfire or rifle cartridges

• Any load not explicitly requiring magnum ignition — over-ignition can create excess pressure and reduced accuracy.
