✅ Primary Application:

Designed specifically for magnum loads in shotshells, such as:

• Heavy hunting loads

• Waterfowl, turkey, or upland game loads

• 12-gauge 3″ or 3.5″ magnum shells

• Large-capacity loads requiring ignition of dense or slow-burning powders

• Certain black powder substitutes in inline muzzleloaders

⚠️ NOT interchangeable with standard 209 primers in load data unless explicitly stated.

✅ Key Features of CCI 209M:

🔹 Hotter and More Powerful Flame:

• Produces a larger, hotter ignition flame, essential for slow-burning powders like:

  • Alliant Steel

  • Blue Dot

  • HS-6

  • Longshot

• Ideal for cold-weather reliability

🔹 Magnum Ignition Strength:

• Ensures reliable ignition of:

  • High-volume powder charges

  • Heavily crimped shotshells

  • Dense buffer materials

🔹 Clean-Burning Formulation:

• Reduces residue and fouling

• Helps maintain consistent performance over extended shooting sessions

🔹 Non-Corrosive and Non-Mercuric:

• Safe for long-term storage and barrel longevity

🔹 Tough, Consistent Primer Cup:

• Designed to withstand high pressures

• Uniform dimensions aid in consistent seating and ignition

---

✅ Use in Inline Muzzleloaders:

• Widely used as ignition sources in 209-primer ignition systems (inline muzzleloaders)

• Effective with black powder substitutes like:

  • Pyrodex pellets

  • Triple Seven pellets

  • Blackhorn 209 (only use with full-strength primers like 209M)

🟨 Standard 209 primers may not reliably ignite Blackhorn 209 – CCI 209M is recommended.

✅ Reloading and Safety Notes:

1. Do NOT substitute CCI 209M for standard 209 primers without:

   • Matching published reloading data

   • Reducing initial powder charges and working up carefully

2. Excess pressure risk:

   • Magnum primers can raise chamber pressure

   • Always follow tested load data

3. Consistent Primer Seating:

   • CCI primers are known to seat slightly tighter in some hulls

   • Ensure primer pocket is clean and sized correctly

4. Hull Compatibility:

   • Works in most 209-sized primer pockets (e.g., Remington, Federal, Winchester)

   • Some hulls may require resizing after multiple firings

✅ Common Hulls and Wad Loads with CCI 209M:

🟨 Use load data that explicitly specifies CCI 209M to avoid pressure issues.
