Shop ammunition online by comparing calibers, checking current availability, and reviewing specifications such as bullet weight, projectile type, muzzle velocity, and intended application. Ammunition covers the loads needed for every firearm in your collection, with options that span practice rounds, defensive loads, hunting bullets, and match-grade cartridges built for precision work.
Here’s what to consider before stocking up:
Buy ammunition online or visit our gun shop in St. James, Missouri to pick up loads in person. Iron Hill Armory also serves customers from nearby cities including Rolla, Cuba, Salem, and Steelville.
Ammunition sales follow federal guidelines and applicable Missouri requirements, which can involve age verification and identification at the point of sale. Shipping timelines and carrier restrictions vary by product, so review checkout information carefully before placing your order.
Storage practices, transportation rules, and range protocols may differ based on circumstances. Contact the shop directly for clarification on purchase requirements, accepted identification, and current store policies.
No, ammunition must match the exact caliber and chambering stamped on your firearm’s barrel. Using the wrong cartridge can damage the firearm or cause serious injury.
Full metal jacket bullets are designed for target shooting and tend to penetrate without expanding. Hollow point bullets expand on impact, making them better suited for defensive use.
Keep ammunition in a cool, dry place away from temperature extremes and direct sunlight. Sealed containers help protect rounds from humidity and corrosion over time.
Grain refers to the weight of the bullet, with one grain equal to roughly 1/7000th of a pound. Heavier bullets typically retain energy better at range while lighter bullets often offer flatter trajectories.
Properly stored ammunition can remain reliable for decades, though signs of corrosion, dented cases, or damaged primers indicate rounds should not be fired. When in doubt, dispose of questionable ammo safely.
Yes, ammunition can be shipped directly to most addresses, though some states and localities have additional requirements. Review checkout information for shipping rules in your area.
Centerfire ammunition has a primer in the center of the case base and is used in most modern firearms. Rimfire ammunition has the primer in the rim and is common in .22 LR and similar small calibers.
Keep enough for regular practice, hunting season, and a reserve for availability gaps. Many shooters maintain a few hundred rounds per active caliber as a baseline.
