Quick Answer
Buying ammo by the case (typically 500–1,000 rounds) instead of by the box saves roughly 10–25 percent per round and far more once shipping is spread across the order; a 1,000-round case of 9mm or 5.56 from SGAmmo, Target Sports USA, Ammo To Go or Palmetto State Armory is the standard bulk purchase. Stick to brass-cased, factory-new ammo from known makers for anything you may store for years, keep it in sealed ammo cans with desiccant in a cool, dry place, and it will last for decades. Check your state’s shipping and quantity rules before ordering, and watch the price-per-round, not the headline case price.
Key Takeaways
- Case lots: 1,000 rounds for 9mm/.223/.22 LR, 500 for .45 and rifle calibers, 250 for shotgun; bulk packs of 100–350 in loose boxes.
- Savings: 10–25% per round versus boxes, plus shipping amortized; biggest on common calibers.
- Best retailers for cases: SGAmmo, Target Sports USA, Ammo To Go, Lucky Gunner, PSA, Brownells, Bulk Cheap Ammo.
- Brass case from major makers for storage; steel case (Tula, Wolf, Barnaul) for cheap range use where allowed.
- Storage: cool, dry, dark, in sealed cans with desiccant; properly stored ammo lasts 20+ years.
- Legal: adult signature ground shipping; California, New York, Illinois and several cities restrict quantities or delivery.
Bulk ammunition is how regular shooters keep the cost of practice manageable, and it is also how people build a reserve against the shortages that hit the market every few years. The savings are real but smaller than the marketing suggests unless you buy right, and ammo stored badly can fail after a few seasons. This guide covers how bulk is sold, what the savings actually are, where to buy case lots, what to buy for storage versus for the range, how to store it so it lasts, and the legal limits. Prices change constantly; the proportions hold.
How Bulk Ammo Is Sold
| Format | Typical quantity | Calibers | Notes |
|---|---|---|---|
| Case | 1,000 rounds (20 × 50 or 10 × 100) | 9mm, .40, .223/5.56, .22 LR | Standard bulk unit; best per-round price |
| Case | 500 rounds (10 × 50 or 25 × 20) | .45 ACP, .38, .357, .308, .30-06, 6.5 CM | Rifle and larger handgun cases |
| Case | 250 rounds (10 × 25) | 12 and 20 gauge | Shotgun ‘flat’ |
| Bulk pack | 100–350 rounds loose in a box | 9mm, .223, .22 LR (325–550 packs) | Big-box store format; modest savings |
| Ammo can / battle pack | 420–1,000 rounds in a sealed can or vacuum pack | 5.56, 7.62×39, 7.62×51, 9mm | Military-style packaging; good for storage |
| Half case | 500 of a 1,000-round caliber | Any | Some retailers split cases |
How Much You Actually Save
Compare the per-round price of a 50-round box at a local store, a 1,000-round case online with shipping, and a bulk pack from a big-box store. On common calibers the case usually comes in 10–25 percent below the box price per round, and because shipping of $15–$35 is spread across 1,000 rounds instead of 50, the landed price gap widens. On less common calibers (.357 Sig, .300 Blackout, 6.5 Creedmoor) the case discount is smaller and the saving comes mainly from shipping amortization. The savings are biggest when you buy during a dip in the market, which is why experienced shooters track prices on AmmoSeek or Wikiarms and buy cases when a brand drops, not when they run out.
Where to Buy Case Lots
SGAmmo is the retailer most often named for honest descriptions and low case prices. Target Sports USA offers free shipping on cases and an Ammo+ membership that discounts further. Ammo To Go, Lucky Gunner and Bulk Cheap Ammo carry broad case selections. Palmetto State Armory and Brownells run frequent case sales with flat-rate shipping. For in-person bulk, big-box stores (Academy, Sportsman’s Warehouse, Cabela’s, Walmart in some states) sell bulk packs with no shipping, and gun shows can be competitive on cases if you know the market price. Use AmmoSeek to compare the landed price per round before committing.
What to Buy: Brass, Steel, Reman, Surplus
- Brass-cased factory ammo from Federal, Winchester, CCI/Blazer, PMC, Sellier & Bellot, Magtech, Fiocchi, Norma: reliable, reloadable, the right choice for long-term storage and any firearm.
- Steel-cased (Tula, Wolf, Barnaul, some Winchester): the cheapest 9mm, 5.56 and 7.62×39, fine for AKs and most ARs, harder on extractors, not reloadable, banned at many indoor ranges; import restrictions have reduced supply.
- Remanufactured (Freedom Munitions, Ammo Inc, local loaders): reloaded brass at low prices; fine for range use from reputable makers, not for storage or defense.
- Military surplus (Lake City, foreign): often excellent value in cans; check for corrosive primers on older foreign surplus and clean accordingly.
- Avoid for bulk: defensive hollow points (buy 100–200 rounds, not cases), specialty hunting loads, and anything from unknown online sellers at prices far below the market.
How to Store Ammo So It Lasts
Ammunition degrades through heat, humidity and the solvents in some lubricants. Stored properly it lasts for decades: the US military routinely fires ammo 30 years old. The rules:
- Cool: under 80°F and away from temperature swings; not an attic or a car trunk.
- Dry: humidity under 50 percent; moisture corrodes brass and can kill primers.
- Sealed: military-style ammo cans (.30 cal, .50 cal, ‘fat 50’) with intact rubber gaskets, with a silica gel desiccant pack inside, renewed yearly.
- Dark: UV degrades plastic shotgun hulls and polymer tips over years.
- Organized: label cans with caliber, brand, quantity and date; rotate by shooting the oldest first.
- Separate from solvents and oils: gun cleaning chemicals migrate into primers.
Properly stored brass-cased ammo has no practical expiry; steel-cased and surplus are more sensitive to moisture.
How Much to Keep
A common rule for range shooters is a year’s worth of practice ammo for each caliber you shoot regularly (for many people, 1,000–3,000 rounds of 9mm or .22 LR and 500–1,000 of rifle), plus a few hundred rounds of defensive or hunting ammo that is rotated annually. Buying in cases during price dips is what makes that reserve affordable; buying in a panic is what makes it expensive. Check your homeowner’s insurance and any local limits on storage quantity, which exist in a few jurisdictions (some cities cap stored ammunition under fire codes).
Legal and Shipping Rules
Bulk ammo ships by ground with an adult signature; buyers must be 18 for rifle and shotgun ammo and 21 for handgun ammo. California requires delivery to a licensed vendor with a background check; New York requires dealer transfer; Illinois needs a FOID; Massachusetts, New Jersey, Connecticut and others require permits or ID; and several cities ban delivery outright. Hazmat fees do not apply to loaded ammunition (only to primers and powder), but carriers surcharge Alaska and Hawaii. Retailers list excluded states; check before ordering a case that cannot be delivered.
Frequently Asked Questions
Is it cheaper to buy ammo in bulk?
Yes, usually 10–25 percent per round for a 1,000-round case versus boxes, and more once shipping is spread across the case. Savings are largest on common calibers bought during price dips.
How long does ammo last in storage?
Decades, if kept cool, dry and sealed. Brass-cased factory ammo stored in ammo cans with desiccant at room temperature and low humidity remains reliable for 20 years and more.
What is the best way to store bulk ammo?
In sealed military-style ammo cans with a desiccant pack, in a cool, dry, dark place away from cleaning solvents, labeled by caliber and date, and rotated so the oldest is shot first.
Where is the best place to buy ammo in bulk?
SGAmmo, Target Sports USA, Ammo To Go, Lucky Gunner, Palmetto State Armory and Bulk Cheap Ammo are the retailers most used for case lots. Compare landed price per round on AmmoSeek first.
Should I buy steel-case ammo in bulk?
Only for range use in firearms that run it well, such as AKs and most ARs, and only if your range allows it. Steel is cheaper but not reloadable and less suited to long-term storage than brass.
Conclusion
Buy cases of brass-cased range ammo from an established retailer when the price-per-round dips, store them sealed and dry, and keep roughly a year of practice ammo on hand per caliber. The savings over boxes are real, the ammo will outlast your interest in it if stored properly, and the stock means a shortage is an inconvenience rather than a crisis. Watch the per-round price including shipping, and let AmmoSeek, not the headline case price, tell you whether the deal is good.
