Name the mystery cartridge

[INEEDAGN]

it measures .308 but it's shorter than the Winchester .308 rifle cartridge. Found it in a trade in truck at work. 9mm on the left just for scale.

Black Out?

How about "Whisper"?

I could/should get down on this. I have some interesting rounds/firearms... Well, at least a few before they all sank on that boat while fishing... Hahaha.

The original parent casing is the .221 Fireball.

Might as well keep it going? Here's the 2 most oddball of our bullet collection.

Is the one on the left a .257 Roberts?


Hmm. The case doesn't look right though, extractor lip not in the case, more outside of it...
Maybe .22 hornet.

I don't really know. Not into older era rounds as much.

But I have this.

Left one is a 3.03 british. I'll give that to you.


Hint for the right one: common bullet in an uncommon case
