Ammunition by Firearm Type
Rifle Ammunition
Mile High's rifle ammunition covers everything from .223 Remington and 5.56 NATO for AR platforms to .338 Lapua Magnum for ELR, with the selection skewing toward match-grade and premium hunting loads. If you're chasing tight groups at distance or building out your match kit, this is where to start. See the full rifle ammunition selection.
Handgun Ammunition
Mile High carries handgun ammunition in the common service and competition calibers - 9mm, .45 ACP, and more - from Federal, Hornady, Fiocchi, and Speer. Whether you're stocking up for the range or sourcing a reliable defensive load, our selection covers both ends of the spectrum. Find your caliber in the handgun ammunition section.
Rimfire Ammunition
Mile High carries .22 LR and other rimfire options from SK, CCI, and others, covering everything from high-volume range training to small game and varmint loads. It's the category that gets overlooked until you need it. See what's available in rimfire.
Shotgun Ammunition
Mile High carries shotgun ammunition from Hornady, Fiocchi, and Winchester in 12, 20 and 28 gauge, covering upland hunting, sporting clays, and range use. Whether you're shooting birds or breaking clays, the selection covers the loads and gauges you need. Find your gauge and shot size in the shotgun section.
Buying Ammunition Online: What You Need to Know
Buying ammunition online from Mile High Shooting is straightforward, but there are a few things every customer should know before placing an order.
Shipping Requirements
All ammunition orders ship via ground carriers only (UPS or FedEx Ground). Ammunition cannot be shipped via air freight or to P.O. boxes. Mile High ships ammunition to most states, but some restrictions apply based on your location. Check the shipping and returns page or contact Mile High directly if you are unsure whether your state or address qualifies for ammunition shipment.
Age Requirements
Federal law requires buyers to be 18 or older to purchase rifle and shotgun ammunition, and 21 or older to purchase handgun ammunition. By placing an order, you confirm that you meet the minimum age requirement for the ammunition type in your cart.
Lot Consistency for Precision Shooting
For competition and long-range shooting where DOPE card accuracy matters, buying the same lot number of ammunition across multiple boxes reduces velocity variation between purchases. Standard deviation and extreme spread can shift slightly between production lots of the same load. When stocking up for a match season, buying from a single lot minimizes the need to re-verify ballistic data. Mile High Shooting understands this pain point for shooters, and will ensure you either get the same lot numbers within an order or get in contact with you if we cannot accommodate this for that order.
Ammunition FAQs
What is the difference between match-grade and standard ammunition?
Match-grade ammunition is manufactured to tighter tolerances -- stricter controls on case dimensions, powder charge weight, and bullet seating depth -- producing lower velocity variation and more predictable trajectories at long range. Standard ammo is built for volume use at shorter distances where shot-to-shot consistency matters less.
Does ammunition expire?
Factory ammunition stored in cool, dry conditions has no practical expiration date. Properly stored commercial ammo commonly remains functional for a decade or more. The main concerns are primer degradation from moisture and temperature swings. For precision competition, test older ammunition over a chronograph before a match.
Can I buy ammo online and have it shipped to my home?
Yes, in most states. Federal law permits direct-to-home shipment for buyers who meet age requirements. Some states - including California, New Jersey, New York, and Connecticut - require shipment to a licensed dealer or impose additional restrictions. Mile High will indicate at checkout if your state has limitations.
Why does ammunition require an adult signature at delivery on orders over $500?
Liability risks on high value orders can be costly for a business. The signature ensures proper delivery and helps keep ammunition costs lower to the consumer. Mile High Shooting will not allow shipment carrier re-routs or hub pick ups. Insurance will not cover those scenarios.
