What is the best way to ensure you have the proper ammunition for your firearm?

• A. Match the information on the firearm's barrel to the information on the cartridge or shotshell before you shoot.
• B. Check the color of the cartridge case.
• C. Rely on the vendor’s recommendation.
• D. Use the same brand as your last purchase.

Answer: (A)

Verifying ammunition compatibility starts by checking the markings on the firearm, typically stamped on the barrel or chamber, and matching that caliber or gauge to the same information on the cartridge or shotshell you plan to load. This direct comparison ensures you’re using the exact size and type the firearm is designed to fire, which is essential for safe operation and reliable performance. Colors on the cartridge case aren’t a reliable indicator, since labeling and color schemes vary by manufacturer and can be misleading. Relying on a vendor’s recommendation can help, but it isn’t a substitute for confirming the actual markings. Using the same brand as your last purchase isn’t a guarantee either, as different models or lots can require different ammunition. When in doubt, consult the owner’s manual or a qualified gunsmith before firing.
