How Many Bullets in a Case or Box? Counts by Caliber

How many bullets in a case or box? A standard retail box holds 50 rounds for most pistol calibers or 20 rounds for most rifle calibers. That is the convention, not a fixed rule, and it changes for rimfire and shotgun ammunition, both covered below. A case is simply a set number of boxes, usually adding up to 500 or 1,000 rounds depending on caliber. Here are the real numbers, caliber by caliber.

How Many Rounds Come in a Standard Box?

The count depends on the caliber, and the pattern splits fairly cleanly between pistol and rifle rounds.

9mm, 50 rounds per box.

.45 ACP, 20 or 50 rounds per box.

.38 Special, 50 rounds per box.

.40 S&W, 50 rounds per box.

.223 / 5.56 NATO, 20 or 50 rounds per box.

.308 Winchester, 20 rounds per box.

30-06, 20 rounds per box.

.30-30, 20 rounds per box.

Most handgun calibers land on 50 rounds per box. Most centerfire rifle calibers land on 20, though some rifle calibers are also sold in 50 round boxes depending on the manufacturer.

How Many Boxes Are in a Case?

A case is a bulk unit made up of a set number of boxes, and the total scales with how many rounds are in each box.

For calibers packaged 50 to a box, a case is commonly 20 boxes, 1,000 rounds total. This is typical for 9mm and 5.56 NATO sold in bulk.

For calibers packaged 20 to a box, a case is commonly 25 boxes, 500 rounds total. This is typical for many rifle calibers.

These are common conventions, not a fixed industry rule. Case size varies by manufacturer and by how the ammunition is sold, retail versus bulk versus surplus.

How Many Rounds Are in a Box of Rimfire Ammo?

Rimfire, almost entirely meaning .22 LR, follows a completely different convention from centerfire pistol and rifle rounds.

Small boxes run 50 or 100 rounds. Bulk packs commonly run 325, 400, or 550 rounds in a single box, sold as one unit rather than broken into a box and case structure the way centerfire ammunition is. This is the biggest packaging difference on this whole topic, and it is easy to miss if you are used to centerfire counts.

How Many Shells Are in a Box of Shotgun Ammo?

Shotgun shells vary more by box count than any centerfire caliber.

12 gauge shells commonly come 20, 25, or even 40 to a box, depending on the manufacturer and the shell’s purpose, target loads and hunting loads are not always packaged the same way. A case is commonly 10 boxes, though the total round count varies with which box size those 10 boxes use.

How Much Does a Box or Case of Ammo Weigh?

Weight scales with caliber more than with round count alone, since a rifle cartridge is heavier per round than most pistol cartridges even though fewer of them fit in a box.

Per 100 rounds, roughly: .22 LR runs under a pound. 9mm runs close to 2.75 pounds. .223 Remington runs close to 2 pounds. .308 Winchester runs close to 3.5 pounds.

Scaled to a standard box, that puts a 50 round box of 9mm at roughly 1.4 pounds, and a 20 round box of .223 at roughly 0.4 pounds. A full case can run anywhere from about 10 pounds to over 30 pounds, depending on caliber and case size, which matters for shipping weight and for how a case is stored.
