This course introduces learners to the terminology and principles used when discussing firearm calibers and projectiles. It covers caliber designations, projectile characteristics, common construction types, and basic identification considerations. Learners will gain a structured foundation for recognizing differences between commonly encountered ammunition and projectile forms.
The course starts with the meaning of caliber and how the term is used across different firearm and ammunition systems. Learners will examine common methods of expressing caliber and cartridge designations. The relationship between caliber, bore dimensions, and projectile dimensions is introduced. Different projectile profiles and construction features are explored at a basic level. The course introduces common projectile materials and jacket configurations.
Learners will examine general visual characteristics that can assist with projectile classification. Basic distinctions between handgun, rifle, and shotgun projectile systems are discussed. The course also introduces terminology used when documenting or describing projectiles. Limitations of visual identification and the importance of verified measurements are addressed. The material provides a foundation for progressing into more detailed ammunition and forensic identification studies.
