The real question
The question isn't "is steel case ammo bad?" It's "does the money I save outweigh the tradeoffs?" For most range shooters, the answer is yes. For carry, competition, and hunting, the answer is no.
What's the difference?
Brass-cased ammo uses a cartridge case made from brass (a copper-zinc alloy). Brass is soft, expands to seal the chamber on firing (called obturation), extracts smoothly, and can be reloaded.
Steel-cased ammo uses a cartridge case made from mild steel, usually coated in lacquer or polymer to prevent rust. Steel is cheaper to produce but harder than brass — it doesn't seal the chamber as well, doesn't extract as smoothly, and cannot be reloaded.
Most steel-cased ammo comes from Russian manufacturers (Tula, Wolf, Barnaul, Bear) or their subsidiaries. Some Chinese-made steel case (Norinco) exists but is less common in the U.S. market since the 1994 import ban on Chinese ammunition.
Price comparison
This is the reason steel case exists — it's significantly cheaper:
| Caliber | Brass FMJ (CPR) | Steel FMJ (CPR) | Savings |
|---|---|---|---|
| 9mm | $0.18–0.24 | $0.14–0.18 | ~$0.04–0.06/rd |
| .223/5.56 | $0.30–0.42 | $0.22–0.30 | ~$0.08–0.12/rd |
| 7.62x39 | $0.30–0.40 | $0.22–0.28 | ~$0.08–0.12/rd |
| .308 Winchester | $0.60–0.85 | $0.45–0.60 | ~$0.15–0.25/rd |
Over 1,000 rounds, that's $40–120 in savings depending on caliber. Over a year of regular shooting (5,000+ rounds), it's meaningful money.

The tradeoffs
Reliability
Steel case is less reliable than brass. The harder material doesn't expand as well to seal the chamber, which can cause more carbon fouling and occasional extraction failures. In a clean, well-maintained modern firearm, the failure rate is very low — maybe 1 in 500–1,000 rounds versus 1 in 2,000+ for quality brass ammo. But it's not zero.
If you're shooting a quality firearm (Glock, CZ, S&W M&P, any mil-spec AR-15), you'll probably run steel case just fine. If you're shooting a tight-tolerance competition pistol or a precision rifle, stick with brass.
Accuracy
Steel-cased ammo is generally less accurate than equivalent brass-cased ammo. This isn't primarily because of the case material — it's because steel-cased ammo typically uses cheaper bullets (bi-metal jackets — a steel core with a thin copper wash, instead of a full copper jacket) and has wider quality control tolerances. Expect 1.5–3 MOA accuracy from steel case versus 1–2 MOA from mid-grade brass in a decent rifle.
For range training inside 100 yards, this doesn't matter. For precision shooting, competition, or hunting, it does.
Wear on your firearm
This is the most debated topic. There are two separate concerns that often get conflated: steel cases are harder on extractors and don't seal the chamber as well, while bi-metal jacket bullets (common in steel-cased ammo but technically a separate issue) are harder on barrel rifling than pure copper jackets.
A much-cited test by Lucky Gunner fired 10,000 rounds each of brass and steel .223 through AR-15 barrels. The steel-cased barrels (which also used bi-metal jacket bullets) showed more throat erosion and accuracy degradation. But — and this is important — even the worst steel-case barrels still had thousands of rounds of useful life remaining, and the total cost of ammo plus a new barrel was still less than shooting brass exclusively.
The math: If steel case saves you $0.10/rd and you shoot 10,000 rounds, you save $1,000. A new AR-15 barrel costs $150–300. Even if steel case cut barrel life in half, you'd still come out $700+ ahead.
For handguns, the wear concern is even less significant. Handgun barrels last 50,000–100,000+ rounds regardless of case material.
Range restrictions
Some indoor ranges prohibit steel-cased ammo because the bi-metal jacket bullets that typically accompany steel cases can spark on steel backstops, creating a fire hazard. Some ranges also can't sort steel cases from their brass recycling. Call ahead if you shoot indoors.
Outdoor ranges rarely care.
The Russian import ban
In August 2021, the U.S. State Department banned new import permits for Russian ammunition manufacturers. This significantly reduced the supply of cheap steel-cased ammo in 7.62x39, .223/5.56, and 9mm. Existing inventory continued to sell, and some manufacturers have shifted production to other countries (Serbia, Bosnia), but the days of $0.12/rd steel-case 7.62x39 are likely over.
This ban made 7.62x39 pricing particularly volatile since Russian manufacturers (Tula, Vympel/Wolf, Barnaul) produced the vast majority of cheap 7.62x39 sold in the United States.
When to buy steel case
Budget range training. If you're shooting 200+ rounds per session and your range allows it, steel case saves real money with minimal downside.
AK-pattern rifles. The AK platform was literally designed to run steel-cased ammo. It's the natural pairing.
Informal plinking. If you're shooting steel targets at 50 yards or just burning rounds on the weekend, steel case is perfect.
When to buy brass
Self-defense and carry. Reliability matters more than price when your life is on the line. Use quality brass-cased JHP.
Competition. Rules may require brass, and the accuracy difference can affect scoring.
Hunting. Accuracy matters. Brass-cased hunting loads from Hornady, Federal, and Nosler are purpose-built for the job.
Reloading. You can't reload steel cases. If you reload your own ammo, brass is the only option.
Indoor ranges. If your range bans steel, you have no choice.
The bottom line
Steel-cased ammo is safe to shoot in modern firearms. It's less accurate, slightly less reliable, and may accelerate wear marginally — but the cost savings are real and substantial over thousands of rounds. For range training in a quality firearm, steel case is a smart choice. For everything else, buy brass.
The best approach: train with cheap steel (or brass FMJ), carry quality brass JHP, and use the savings to buy more trigger time. That's what most experienced shooters do.
