Understanding COL and its Importance
Cartridge Overall Length (COL) is crucial for safe and reliable functioning. An incorrect COL can lead to malfunctions or damage to your firearm. Always meticulously measure your loaded rounds to ensure they are within the specified range.
Safety First: Essential Reloading Precautions
Reloading ammunition is inherently dangerous. Always prioritize safety:
- Wear safety glasses and hearing protection.
