5.56 NATO vs 7.62x39

The usual version of this argument is about ballistics. The useful version is about what you will actually spend, and on that question both cartridges have a claim — depending entirely on which shelf you buy from.

7.62x39 owns the floor. The cheapest steel-case imports are the least expensive centerfire rifle rounds on the market. But the catalog behind that floor is shallow, and the moment you want brass cases, expanding bullets or a case of anything, 5.56 and .223 have the deeper and better-supplied market. Here is where each one wins, with both indexes live on this page.

What actually differs between 5.56 and 7.62x39?

The projectiles are not in the same class. 5.56 NATO fires a .224-inch bullet, typically 55 to 77 grains, fast. 7.62x39 fires a .311-inch bullet, almost always 122 to 125 grains, considerably slower. That single difference drives everything else.

The 5.56 bullet's speed and light weight give it a flatter trajectory and very little recoil, which is why it is easy to shoot well and easy to shoot quickly. The trade is that it loses effectiveness as velocity drops, so short barrels and long distances both work against it.

7.62x39 starts slower and arcs more, which puts a practical ceiling on it somewhere around a couple of hundred yards for most shooters. In exchange it delivers a heavy .30-caliber bullet that behaves more like a short-range deer cartridge than a varmint round. Recoil is noticeably firmer than 5.56 but not unpleasant.

Neither is a general upgrade over the other. They are two different answers to the same design problem, and the price data reflects two different supply chains.

Which one is cheaper per round right now?

Both, depending on where you look. Compare the floor line and the average line on these two blocks:

The floor goes to 7.62x39 and the average goes the other way. That is not a quirk of the day we published this — it is structural. The cheap steel-case imports that set the 7.62x39 floor are a narrow band of the market, and once you step off that band the cartridge has very little volume production behind it. 5.56 and .223 have a wide middle: dozens of domestic and imported brass-case options competing on price.

You can see the same thing in how much of each market is available by the case:

The 7.62x39 bulk grid is nearly the entire bulk market for that cartridge. The .223/5.56 grid is the top of a much longer list. If you buy in volume and care about having options when one retailer runs dry, that depth has value that the floor price does not capture.

Why does 7.62x39 get expensive as soon as you leave steel case?

Because the affordable tier is an import story, and the rest of the cartridge is a niche-production story.

Steel-case ammunition is cheap because steel is cheaper than brass and the factories making it run at enormous scale for non-US markets. Availability of those imports has shifted more than once over the years, and it can shift again — which is exactly why this cartridge's price history is more volatile than 5.56's. We cover that dynamic generally in why ammo prices move, and the case-material trade-off itself in steel case vs brass.

Here is what the non-steel tier looks like:

7.62x39 Beyond the Steel-Case Floor

Compare those against the .223/5.56 grid above. The same money buys you a much wider field in 5.56. If your range prohibits steel-case ammunition — plenty of indoor ranges do, usually over the bimetal jackets rather than the cases themselves — the 7.62x39 cost advantage largely evaporates before you have fired a round.

What do the rifles themselves cost?

Closer together than the argument implies. Entry-tier examples of both platforms:

Read the chamberings in both grids rather than assuming. The AR grid includes .300 Blackout and .350 Legend rifles alongside the 5.56 guns, and the AK-pattern grid includes 9mm WASR-M carbines that are not 7.62x39 at all. That is a catalog reality, not a recommendation.

Either way, a complete rifle is an FFL transfer — see how buying a gun online actually works before you order, because the transfer fee is a real line item that neither grid shows.

The purchase price is also the smaller number over any reasonable ownership period. At a few thousand rounds a year, the ammunition outspends the rifle quickly, which is the argument for picking the cartridge first and the rifle second. If you want a sense of what "a few thousand rounds" means in practice, we worked through it in how many rounds it takes to get good.

Which one is better for hunting?

7.62x39, for most people, within its range — with the enormous caveat that legality is a local question.

A 123- or 125-grain expanding .30-caliber bullet at moderate velocity is a well-proven short-range deer proposition, and it is one of the few genuinely cheap ways into a deer rifle. 5.56 with a heavy expanding bullet works on deer-sized game too, but it is legal in fewer places and leaves less margin for imperfect shot placement.

7.62x39 Expanding Loads, Cheapest First

Notice where the expanding loads land relative to the steel-case floor in the index above. A hunting 7.62x39 load is not cheap ammunition — it just sits in a cartridge whose practice ammunition is.

What about suppressors and subsonic loads?

Neither cartridge is the natural answer here, and 7.62x39 is the weaker of the two.

Subsonic 7.62x39 exists — there is one in the picks above — but the cartridge was not designed around it, and subsonic loads in a rifle built for supersonic pressure frequently will not cycle the action reliably. 5.56 subsonic is worse still. The cartridge that was purpose-built for this job is .300 Blackout, which is why it exists at all.

If quiet is the actual goal, read the suppressor buying guide first and choose the cartridge around that decision, not the other way around. NFA paperwork, wait times and state eligibility are the constraints that matter, not the ammunition price.

What does the ecosystem around each rifle cost?

This is where the real difference hides.

Optics. Mounting a modern optic on an AR is solved — a flat-top receiver and a mount. On an AK-pattern rifle it is a genuine decision involving side rails, rail covers or a dust-cover mount of varying quality. Neither is difficult, but only one is free. If you are choosing an optic at the same time, red dot vs LPVO covers that trade separately.

Magazines. Both platforms have deep, cheap magazine markets, and both have junk at the bottom of them. How many you actually need is a question we answered in how many magazines do you need.

Ammunition selection. The AR shooter can change bullet weight, case material, pressure and terminal design across a wide field, as our best 5.56 and .223 ammo picks show, and can change the barrel's twist rate to use more of it. The 7.62x39 shooter has far fewer choices. For a lot of people that simplicity is a feature.

Shipping. Both are subject to the same state-level ammunition shipping rules, and some of the best cost-per-round listings come from retailers that cannot ship everywhere — check shipping restrictions before you plan a case purchase around a price.

So which should you buy?

Pick 7.62x39 if your shooting is inside 200 yards, you want a cheap high-volume practice cartridge and you are content with steel-case imports, or you want an inexpensive short-range hunting rifle. Track the 7.62x39 index and buy cases when the floor drops, because this cartridge's supply is less stable.

Pick 5.56 if you want distance, lighter recoil, or the ability to change what your rifle does by changing ammunition. The .223 and 5.56 market is deeper at every tier above the floor, and you will find a load for whatever the rifle's job turns out to be.

If you are undecided and buying your first centerfire rifle, the deeper ammunition market is worth more than a few cents per round. If you already own one and are considering the other, the honest answer is that you are buying a second rifle, not saving money.

Either way, set an alert on the cartridge you land on and buy on the dips rather than the day you run out:

For the 5.56 side of that decision, start with best 5.56 and .223 ammo, and if the .223-versus-5.56 chamber question is still open for you, we settled that one separately.

Frequently Asked Questions

Is 7.62x39 cheaper than 5.56?+
At the very bottom of the market, yes — the cheapest steel-case 7.62x39 sits below the cheapest bulk 5.56 in our live index. Above that floor it reverses: brass-case, hunting and match 7.62x39 all cost more than their 5.56 equivalents, because there is far less domestic production. Both live indexes are on this page, so compare the floor line and the average line rather than one headline number.
Which has more stopping power, 5.56 or 7.62x39?+
7.62x39 fires a much heavier, larger-diameter bullet at lower velocity, so it hits harder at short range and penetrates barriers differently. 5.56 is faster, flatter and easier to shoot accurately at distance. Neither is decisively superior; they are optimized for different ranges.
Can an AR-15 shoot 7.62x39?+
Only with a dedicated 7.62x39 upper or a rifle built for it — the bolt, barrel and magazines all differ from a standard 5.56 AR. Conversions exist and work, but feeding has historically been the weak point because the cartridge is more tapered than 5.56. If you want the cartridge, buying a rifle designed around it is usually the cleaner path.
Is 7.62x39 good for deer hunting?+
Inside its range, with an expanding bullet, it is a commonly used short-range deer cartridge, roughly comparable to a .30-30 in application. The critical issue is legality: states vary on minimum calibers, straight-wall requirements and whether semi-automatic rifles may be used. Check your state's current regulations before you buy.
Why is 7.62x39 ammo so variable in price?+
Its cheap end depends heavily on imported steel-case ammunition, and import availability has shifted several times over the years. Domestic brass-case production exists but at much lower volume than 5.56, so when imports tighten there is no deep domestic supply to absorb it. That is why the floor and the average in the index below sit so far apart.
Which is cheaper to own overall, an AK or an AR?+
Rifle prices for entry-tier examples of both are visible in the grids on this page, and the gap is usually smaller than the internet suggests. The larger cost differences show up in the ecosystem: optic mounting, magazines, spare parts and how much ammunition you plan to shoot per year.
