What is NOT one of the primary safety rules for firearm handling?

Loading a firearm before use goes against one of the fundamental principles of firearm safety. Firearms should always be considered loaded, and handling them as if they are loaded is crucial. The primary safety rules are designed to ensure that firearms are used safely and responsibly.

Pointing the muzzle in a safe direction prevents accidental discharge from causing harm, and identifying your target ensures that you know what you are aiming at, which is essential for safe shooting. Additionally, keeping the safety on until ready to fire helps to prevent unintentional discharges. Thus, the act of loading a firearm before use doesn't fit within these critical safety rules, emphasizing the importance of handling firearms responsibly at all times.
