California Firearm Safety Certificate Practice Test

Some firearms, specifically .22 caliber firearms, may look very similar. However, using rimfire cartridges in a centre-fire firearm can be dangerous. Rimfire cartridges are designed to be struck by the firing pin on the edge of the cartridge, while centre-fire cartridges are designed to be struck in the center by the firing pin. Attempting to use the wrong type of cartridge in a firearm can cause serious damage to the firearm and potentially harm the user. Therefore, it is important to always use the correct type of cartridge for your specific firearm.
