Canadian Restricted and Non-Restricted Firearm Safety (CRFSC) Practice Exam

When the firing pin strikes the primer, it causes the primer to detonate. This initiation of the primer creates a small explosion, which ignites the gunpowder contained within the cartridge. The rapid combustion of the gunpowder produces high-pressure gas, which ultimately propels the bullet down the barrel and out of the firearm. This sequence of events is critical for the functioning of a firearm, as the detonation of the primer is the first step in the chain reaction that leads to the firing of the bullet. Understanding this process is essential for safe firearm handling and operation, as it underscores the importance of maintaining the integrity of the primer and cartridge in general.
