Caliber?
Where on the case are you talking about?

I am going to assume you are talking about the cannelure on the case neck.
It is there to keep the bullet from being driven deeper into the case during feeding.

Yeah, I've noticed that on some brass. Only thing I can think of, is it's there to prevent bullet set-back. On a factory round, it's right at the base of the bullet.

Ahh that makes perfect sense:o

Found a couple of WW marked 45acp`s during one of my range rat trips a few weeks ago, been wondering about that "belt" ever since. Thanks alot:)

I actually thought it was some kind of pressure indicator. Doh!

I've seen the dimple line on 9x19 FC cases, both nickel and brass.

Federal has been doing this on handgun cases for years. And you are correct. It's to keep the bullet from setting back...Winchester, Remington and the rest of the case manufacturers do it on some cases and not on others...It's one of the things I look for (it must be cannelured to insure of no set back) when purchasing my CCW ammunition...
