I'm just curious as to how you can tell the difference between bullets when they arent in a box. I know that there are letters on the bottom of the bullet but ive found that they dont match up with the type of bullet they actually are so a little help please and thank you.

Almost all cartridge cases have identification on the case heads,but I have never seen identification on bullets.

Yah because im shooting Federal 180 grain partions for a 30.06 and on the bottom it say 30.06 Fed F C H E and im also wondering what the F C H E would stand for.

Are you talking about just bullets or bullets in a cartridge case?

Federal Cartridge High Energy

There is no way of destinguishing the different bullets just by looking at a loaded case, with few exception.

Here is a list of the major ammo manufacturers and what their head stamps are.

Federal = - F C - for Federal Cartridge or -F C H E - for Federal Cartridge high energy.

Remington = R P for Remington Peters

Winchester = Winchester

Hornady = Hornady or Frontier

Weatherby = Weatherby

If its just bullets, you can Mic them then weigh them.

Speer used to stamp GS on the base of their grand slam bullets. I dont know if they do so anymore. I've never herd of any other manufacteres marking their bullets,although It's possiable they didso without my knowing.

You can I.D. a Nosler Partition, there's lead exposed at the base. Loaded factory ammo is tough as far as what grain bullet you have.
