How to Buy Ammo in Bulk: A Step-by-Step Method

Buying ammo in bulk is the easiest way to bring your cost per round down, if you do it right. Ask where to buy bulk ammo on r/ammo and you will get a long list of store names; the answers worth listening to share a method: settle on a load, compare the delivered price per round, and buy a case from a store that ships quickly. Here it is, step by step.

1. Decide what bulk means for you

A 1,000-round case, or a pallet? For most people, bulk means a case of a caliber they shoot often, such as 9mm, 5.56 or .22 LR. Case sizes vary by brand; see how many rounds are in a case of ammo.

2. Test a box before you buy a case

Buy one box, shoot it in your gun, then buy the case of the same product. That is our advice. In one thread, a buyer reported repeated failures to fire from a case of factory seconds.

3. Compare delivered cost per round

Search AmmoSeek with the shipping filter set to free or low shipping, then compare price plus shipping, divided by rounds. Watch how a store charges shipping: one buyer ran into a store that charged shipping per box, so doubling the order doubled the shipping. Count sales tax too, since it varies by store and state.

4. Favor stores that ship fast and list real stock

Cheaper sellers can leave you waiting weeks to ship, while an established store ships in days. One buyer described a restock text that sold out again before he could check out. And check a big order when it lands: one longtime buyer said carriers had mishandled three of his 1,000-round orders over the years, even from stores he trusted.

5. Watch for sales, and do the membership math

Deal hunters watch r/gundeals and big-box store promotions for case deals. Annual shipping memberships pay off only if you order often enough to cover the fee. Ours is Brass Club; run the numbers on it the same way.

6. Store it properly

Keep bulk ammo dry, sealed and indoors. In Phoenix, keep cases out of garages, sheds and vehicles in summer. See how long ammo lasts in storage.
