Quick Summary

Semifixed ammunition consists of complete rounds for artillery where the projectile is detachable from the cartridge case. This design allows for adjustments to the propelling charge by removing increments. After adjustment, the projectile is loosely inserted into the case. This differs from fixed ammunition, where all components are securely joined, and separate-loading ammunition, which consists of three distinct parts: projectile, propellant, and primer. Ammunition is classified by caliber, with larger calibers generally considered artillery.12
