The plastic version of the classic 50-cal can, with an O-ring seal.
You can order ammo online in much of the U.S., but the rules change at the state line. Here's how it works, where to start, and how to store it once it lands.
We may earn a commission when you buy through our links. Affiliate disclosure

Compare prices on AmmoSeek, a search engine for in-stock ammo across online retailers, then buy from a retailer that ships to your state. Count the cost per round with shipping included, not the box price. Store it sealed, cool and dry. None of the links on this page are affiliate links yet; we haven’t joined any ammo retailer’s program.
Age. Under federal rules, a licensed dealer can’t sell rifle or shotgun ammo to anyone it believes is under 18, or handgun ammo to anyone under 21 (27 CFR 478.99). Many states add their own rules.
Shipping. Some states and cities restrict or block ammo shipped to your door. Lucky Gunner, for example, says it can’t ship to Alaska, Hawaii, Massachusetts, California, New York City, Chicago and several nearby cities, or Washington, DC.
California. Online orders have to go to a licensed California ammunition vendor, who runs the state’s eligibility check before handing it over (California DOJ).
Laws change. This isn’t legal advice. Check your state and local law before you order. Our safety & legal policy explains how we cover these topics.
SAAMI, the industry’s standards body, says to keep ammo in its original box or a container made for it, somewhere cool and dry, away from solvents and heat, and not in a hot car. Keep it separate from firearms and out of reach of kids. A sealed, lockable can like the MTM AC50C handles the humidity part. More in our safes and ammo storage guide.

An O-ring and a brass bail latch keep out water and dust.
