Steel-Case vs Brass-Case Ammo: What to Know

Steel-case ammo is the low-cost option on many ammo shelves. Brands like Wolf made it a familiar sight at ranges. It works well in many guns, but it comes with a few trade-offs worth knowing before you order a case of it.

What steel case is

Most ammo uses a brass case. Steel-case ammo swaps the brass for steel, which costs less. The steel gets a coating, usually lacquer or polymer, to stop rust and help it slide in and out of the chamber.

Steel case is most common in calibers made for high-volume shooting, like 7.62x39, 9mm and .223 Remington. In our listings, steel case costs less per round than brass in both 9mm and 7.62x39, and its prices sit in a much tighter band, as the chart at the top shows.

“Steel case saves money. Brass case saves hassle.”

The common worries

• Extraction: brass expands to seal the chamber and then springs back. Steel springs back less. Some guns, often ones with tight chambers, can have trouble pulling out fired steel cases.
• Dirtier shooting: a looser seal can let more powder residue blow back into the action. Expect to clean more often.
• Wear: shooters argue about whether steel wears extractors faster. If your gun's maker warns against steel case, follow that advice.
• Range rules: some indoor ranges ban steel-case ammo, and some ban bullets with steel in them. Many ranges check with a magnet. Ask before you go.
• Reloading: you can't reload steel cases. If you reload, you want the brass back.

“Check your range rules before you pack the steel.”

When steel case makes sense

Steel case is a good fit for plinking and practice in guns that run it well. Rifles built with looser chambers, like many AK-pattern rifles chambered in 7.62x39, were designed around it. Plenty of handguns and rifles run it fine too. Try a box before you order a case.

When brass is the better pick

• Defense loads: stick with quality brass-case ammo you have tested in your gun.
• Accuracy work: brass loads are usually more consistent for paper and precision shooting.
• Reloading: brass can be reloaded several times. Steel cannot.
• Indoor ranges: brass is welcome almost everywhere.
• Guns that don't like steel: if your gun has trouble extracting steel, brass solves it.

“If you reload, stick with brass.”
