30 Reece

[7000grain]

The .30 Reece is a wildcat cartridge with limited published load data, but here’s the most reliable information available from shooting communities and historical references:

Supersonic Loads
1. 110–125 gr Bullets

Key Considerations
3. Pressure Management:
• Start 10% below max loads and work up.
• Case capacity is similar to .32-20 WCF but stronger .
2. Brass Prep:
• Formed by running .38 Special brass through a full-length sizing die .
• Trim to 1.15–1.20” (varies by chamber).
3. Twist Rate:
• Most barrels have 1:8”–1:10” twist for stabilizing heavy bullets .
4. Powder Selection:
• Fast to medium burn rates (N110, 4198, 2400) work best.
• Avoid slow powders (e.g., H4350) due to small case volume.
Recommendations
• For metallic silhouette shooting: 190 gr bullets with N110 or 4198.
• For suppressed use: 220 gr cast bullets with Trail Boss.
• Always verify COAL for your firearm (typically 1.55–1.65”).
Note: The .30 Reece lacks SAAMI specifications, so consult a gunsmith and prioritize published data from trusted wildcat sources like Handloader Magazine or Cartridges of the World.
