Seen something like this when someone tired making 444 Remington out of 06 brass.
Could be 400 Whelen or 400 Brown Whelen
I have seen similar when 308 was fired in an 30-06 chamber. The ones I found came from a garand that had had the insert pull out with a case being extracted.
Which ever shell holder fits it would be a place to start.

OK People. Enough of this idle chit-chat.

Look up the 411 Hawk -- Z Hat has information on that.
It is the biggest bullet diameter 06 family cartridge that I know of. It could well be that. The shoulder is more like a forward belt, as far as Function.
Looks like Fred retired or something, but you can poke around these links to see what you could find on the Hawk Cartridges.

06 parent case, neck is too short for the 400 Whelan.
Case is too long for the .411 Hawk, with too short a neck.

338-06 Ackley Improved if I were to guess, what does the case mouth measure ?
Now that I've shot my skeet rounds for the day and got rained out on sporting clays this afternoon, real measurements are:
Mouth ID: .400
Case length: 2.47
Shoulder: 2.270-2.300 (4 cases measured, trying to measure shoulder without an optical comparator is a crap shoot)
R-P headstamped 30-06 cases.
Not shot in a 30-06 for sure. I ran into a .308 Winchester marked case at the range one day that had obviously been fired in a 30-06 rifle. It was blown out straight like the case in your pictures. I figure someone had chambered a .308 in a 30-06 rifle without noticing the mistake. james
I shamefully admit that I fired an entire 8 rd. M1 Garand clip loaded with .308 Win. (7.62mm Nato) ammo in a Garand one time. That's just about exactly how the results appeared. It kicked like a mule! Afterward, I was picking up brass and thought to myself, "I guess somebody didn't want this .45-70 brass!" Then I looked at the headstamp, and then thought about my aching shoulder, and 2+2 = 4.

Kind of looks like an "Oopsie, I ran the reamer for a .400 Whelen in too far" to me.
Otherwise, that is a very short neck for anything in the .40 caliber range of rifle rounds.

Whats the headstamp say?
My headstamp said AFF, it was Australian military surplus. I don't remember the year offhand, but it's very good ammo in the correct rifle I still have some battle-packs of it and it shoots great out of my M1A.
For the third time, 30-06 as the parent case. There was a whole bunch of these in the scrap brass bucket. and some that looked like legitimate 400 Whelen. And a whole bunch of other wildcat brass.
Including one with the sharpie notation "shot on the same day as the blow-up".
Makes you wonder who is shooting what when you are on the line. It was at a private club that has 700+ active, life and probationary members. Don't have a clue who it is. I've done a fair amount of cartridge conversions over the years, I've never seen any thing with this short a neck. Even the 300 Savage has a longer neck, if I recall correctly.
Case is too long for the .411 Hawk, with too short a neck.
The Monroe Muskrat Killer? That is about as dangerous game as we get in SE Michigan.
Makes me think of picking up the cases at a rifle ranges near Houston Intercontinental, factory 8x57 rounds fired in a 30-06.
