Proof marks on a Browning rifle indicate that the firearm has undergone rigorous testing to ensure its safety and reliability. These marks typically signify that the rifle has been fired with a proof load, which is a higher pressure cartridge than standard ammunition, to verify the integrity of its construction. Proof marks also provide information about the manufacturer, country of origin, and sometimes the year of proofing, demonstrating the rifle's compliance with safety standards.
