Which of the following is the best way to make sure you have the proper ammunition for your firearm?

• A. Match bullet weight to the firearm’s capabilities
• B. Match the information on the firearm's barrel to the cartridge or shotshell before you shoot
• C. Try different brands until something fits
• D. Use the largest caliber available

Answer: (B)

Checking the firearm’s markings and matching them to the ammunition before you shoot is the safest and most reliable way to ensure you have the proper ammo. The barrel is stamped with the exact caliber and cartridge type the gun is designed to fire. By confirming that the ammo’s labeling matches those markings, you ensure the round will chamber correctly and operate within the gun’s designed pressure limits. This direct check helps prevent dangerous mismatches that could cause damage or injury. Other ideas like guessing by bullet weight, trying brands until something fits, or using the largest caliber available do not guarantee compatibility and can create unsafe conditions.
