You Will Need
- Proof of age
- Internet access (optional)
Know the law
Have proof of age: federal firearms laws require individuals to be 18 years old to buy ammunition for rifles or shotguns and 21 to buy bullets for handguns.
Know your target
Consider what you'll be shooting -- competitive shooters need ammunition geared for accuracy, while hunters should measure effectiveness based on specific game.
Match bullets with guns
Examine the gun or guns you're buying ammunition for -- different caliber arms require different sized bullets. Use the letters after the number, or caliber, to ensure you're buying the appropriate ammunition for your specific gun's barrel length.
Visit a gun shop and test the ammunition that fits your gun. Judge ammo based on its ability to penetrate a target without deflecting off or passing through -- both can cause collateral damage. Examine the bullet’s casing and the amount and type of material at its tip; these factors affect expansion on impact.
Buying in bulk? Go online to buy ammunition. Be advised: while internet retailers may offer competitive prices, many have strict rules about selling large quantities of bullets. They and all gun owners are responsible for ensuring people who purchase guns and ammunition behave safely and responsibly.
