Surplus Ammo Guide: Is Military Surplus Worth Buying?
June 6, 2026 · AmmoBin.com
Military surplus ammo can be a cheap way to feed milsurp rifles — but it comes with quirks like corrosive primers and Berdan priming. Here's what to know before buying.
Common surplus calibers
Classic surplus includes 7.62x54R (Mosin-Nagant), 8mm Mauser, .30 Carbine, and 7.62x39. It's often inexpensive and sold in spam cans or battle packs that store extremely well.
Watch for corrosive primers
Much older surplus uses corrosive primers — totally shootable, but you must clean the same day with a water-based solvent to prevent bore rust (see cleaning after corrosive ammo). Most surplus is also Berdan-primed, so it's not reloadable (Boxer vs Berdan).
Is it worth it?
For milsurp rifle owners shooting volume, yes — it's cheap and stores well. Just budget for diligent cleaning. Compare live prices for 7.62x54R and 8mm Mauser.
