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

Question: 1 / 400

What can residues in the chamber or barrel cause?

Improved firing performance

A safe shooting experience

Serious pressure build-up

Residues in the chamber or barrel can lead to serious pressure build-up during firing. When residues such as carbon, unburnt powder, or other contaminants accumulate, they can obstruct the normal passage of the bullet through the barrel. This obstruction can create excessive pressure, increasing the risk of malfunctions like a squib load or even catastrophic failures that could damage the firearm or cause injury to the shooter and bystanders. Therefore, maintaining a clean firearm is crucial for both performance and safety.

The other options do not accurately reflect the consequences of such residues. Improved firing performance and reduced cleaning time contradict the negative impacts of debris in the firearm. Additionally, a safe shooting experience cannot be assured when any obstruction or residue poses a risk of pressure build-up.
