What is a common cause of squib loads in ammunition?
Answer: Reloaded ammunition assembled with an insufficient or missing powder charge
Improperly reloaded cartridges with missing or insufficient powder charges are a leading cause of squib loads, which is why inspecting reloads is critical.
How should you check for a barrel obstruction after a suspected squib load?
Answer: Use a cleaning rod inserted from the muzzle end with the action open and firearm verified unloaded
After applying PROVE and confirming the firearm is unloaded with the action open, a cleaning rod inserted from the muzzle will detect any lodged bullet.
How should misfired cartridges be properly disposed of?
Answer: Soak them in water to neutralize the primer and powder, then dispose of safely or give to range personnel
Soaking misfired cartridges in water neutralizes any remaining live primer or powder, making them safe for disposal.
What precaution best protects a shooter if a hangfire occurs?
Answer: Keeping the firearm pointed in a safe direction for at least 30 seconds before opening the action
By keeping the firearm pointed in a safe direction for at least 30 seconds, any delayed ignition from a hangfire will discharge harmlessly in a safe direction.
What is the key difference between a misfire and a hangfire?
Answer: A misfire results in no discharge at all; a hangfire results in a delayed discharge
A misfire produces no ignition and the cartridge never fires, while a hangfire eventually discharges after a noticeable delay following the primer strike.
If you hear an unusual reduced 'pop' or feel significantly less recoil than normal while firing, you should:
Answer: Immediately stop firing, keep the muzzle pointed in a safe direction, and check for a barrel obstruction
A reduced sound or recoil suggests a possible squib load; firing another round into a barrel obstruction can cause catastrophic and potentially fatal barrel failure.
In Canadian firearm safety, what does the PROVE procedure accomplish?
Answer: It is a systematic procedure to confirm a firearm is completely unloaded and safe to handle
PROVE (Point in safe direction, Remove ammunition, Observe chamber, Verify feeding path, Examine bore) is the Canadian standard procedure to confirm a firearm is unloaded and safe.
