Where to Start

Buying ammo is easy once you know three things: what your gun shoots, what you are shooting it for, and how much you need. Work through these steps and you will buy the right ammo every time.

Step 1: Find your caliber

Your caliber is stamped on the barrel (or the slide on most pistols) and listed in the owner’s manual. Match it exactly. Similar-sounding rounds are not interchangeable, and the wrong ammo can damage your gun or hurt you.

  • Not sure what the numbers mean? See Caliber.
  • Common questions are answered in the Ammo F.A.Q.

Step 2: Pick the bullet for the job

  • Practice and plinking: full metal jacket (FMJ) is affordable and feeds reliably.
  • Self-defense: quality hollow points (JHP) from a name brand. Test a box in your gun first.
  • Hunting: soft point or bonded bullets made for the game you are after.
  • Learn the differences in Bullet Types.

Step 3: Choose your ammo type

Step 4: Buy smart

  • Compare price per round, not price per box.
  • Buy in bulk when prices drop.
  • Some ranges do not allow steel-case or steel-core ammo, so check before you go.
  • Stick with brands you trust. See Ammo Manufacturers.
  • Check your state’s laws on buying and shipping ammo.

Step 5: Store it right
