It appears as if all were seated with the same seating die. 2nd one looks like 30.30. Other than that - no clue.

Looking at the 280 Enfield, it looks like the Grendel is slightly scaled down from it.

Indeed. I've always thought of 6.5 Grendel as a scaled-down .280 Enfield, and 6.8 SPC as a scaled-down 7.62 NATO.

Here is my offering to the thread:

Wow, that's a toughie, but I'll make a wild guess.

L. to r.: .376 Steyr; .375/.348 Winchester; .375x56R; .375x55 Swiss; .375/.284 Winchester; .375-08 Winchester.

You cheated and did an image search, didn't you.

I all of a sudden have a big bore urge that I can't seem to make go away.

As if anybody could possibly identify all of those oddball wildcat cartridges any other way?

Sort of belies the "wild guess" then, doesn't it?

30-30 and 8x50 lebel

Rasp65,
Very good, 8mm Label, I thought that one would be tougher of the two to identify, but no the other one is not a 30-30.

The Label was the first military small bore cartridge using smokeless powder adopted by a world power(France, 1886).

8mm Lebel is very distinctive, so (for me, at least) quite easy.

But, there are many cartridges of similar shape to the second one. I'll say .30 US Army (aka .30 Krag).

Stanc,
You got it, .30 Krag(30/40 Krag) was the first small bore cartridge adopted by the US military to use smokeless powder.

I have seen this one before... I just cant remember where!!

[stanc]

Looks an awful lot like 6mm US Navy (the first really small bore cartridge adopted by the US military to use smokeless powder).
