What is the case?

[MymuttBear]

I picked up the case on the right while at the range the other day. Can anyone shed light on what it is? 5.56 next to it for comparison.

What does the bottom of the case have for marking?

300 Blk doesn't have a rebated rim, it shares the same case as 5.56.

Yah, more than likely.

Internet grab:

I'll admit it was a quick look. I thought it looked just like the one on the left but shorter.

Assuming you shoot the caliber what firearm do you have? Only thing I could find, quick search, was it's a handgun round.

I do not shoot nor load for that caliber, I occasionally find them when picking brass.

Handgun & "PDW" type round.

Much controversy over its usefulness or lack thereof.

Fan of it. Others are not.

Originally only FN made firearms for it, both handgun & "PDW" (semi auto carbine for US market).

However nowadays several others are making them as well. Mostly handguns.

Still a niche use defensively, IMO.
