If you have ever stood in front of an ammo shelf and wondered who actually makes all those boxes, this list is for you. It covers the makers shoppers see most often, where they are based, and what each one is known for. Every name links to its live listings, and the full brand directory has the rest.

The chart at the top shows which brands fill the most in-stock listings on Gun Search Engine right now.

“A few big names fill most of the shelf. Dozens of smaller makers fill the gaps.”

Major US makers

  • **Federal:** based in Minnesota. Makes a wide range of target, hunting and defense loads in rifle, handgun and shotgun.

  • **Remington:** made in Arkansas. Known for hunting rifle and shotgun loads and bulk range ammo.
  • **Hornady:** family-owned and based in Nebraska. Known for bullets, defense loads and precision rifle ammo.
  • **CCI:** based in Idaho. Best known for rimfire ammo and primers.
  • **Speer:** based in Idaho. Known for handgun defense loads and bullets for reloaders.
  • **Sig Sauer:** the gun maker also makes ammo in the US, mostly handgun and rifle loads built around its own guns.

  • **Double Tap Ammunition and Buffalo Bore Ammunition:** smaller US makers known for heavy handgun and hunting loads.

One parent, many brands

The name on the box is not always the company that owns it. Federal, CCI, Speer and Remington ammo sit under the same parent company today. Magtech and Sellier & Bellot are both part of the same Brazilian group. Brands under one owner can still keep their own plants, product lines and reputations.

This matters less than people think when you shop. What counts is the load: bullet type, weight and the job it was built for.
