Steel vs Aluminum vs Brass Cases: Cost vs Performance
June 22, 2026 · AmmoBin.com
Practice ammo comes in brass, steel, and aluminum cases. Each is a different trade-off of cost, reliability, and reloadability. Here's the quick decision guide.
The three at a glance
- Brass — most reliable, reloadable, corrosion-resistant, allowed everywhere; costs most
- Steel — cheapest in bulk, not reloadable, can corrode, banned at many indoor ranges, more extractor wear over time
- Aluminum — light and cheap, not reloadable, soft case; fine for casual range use only
Which to buy
Brass is the best all-rounder, especially if you reload or shoot indoors. Steel saves money for high-volume outdoor shooting (e.g. 7.62x39). Aluminum is a budget option for casual plinking. See the deeper brass vs steel comparison.
Dirtier ammo means more cleaning (cleaning). Compare live prices for 9mm and 7.62x39.
