Can anyone ID this round?

[press-1-for-english]

First and foremost, if this thread is in the wrong spot or shouldn't exist at all please let me know and I will attempt to delete it or ask a honcho to.
OK
My buddy found this on a key chain at the flea market.
It was drilled for the loop and has no primer. The head stamp is REM on top(12 o'clock) and 45 on the bottom(6 o'clock)
Any information will be greatly appreciated.

Is 0.420 the diameter of the neck or the base of the cartridge?

 

[press-1-for-english]

.420 is the diameter of the bullet/projectile.

Looks to be close to a 44/40 but it looks to be rimless.

Can you tell from the primer pocket whether it is Berdan or Boxer primed?......Ben

It is confusing. I hope its not some unidentifiable old wildcat. The REM 45 head stamp is weird,too.

I asked my buddy to send me a picture because I wouldn't know the difference but if i remember correctly it was one hole in the center.

Is the bullet an FMJ or a soft nose?

 

[press-1-for-english]

FMJ like ball ammo.

I do not recognize it. Nor do I know what the “REM” headstamp could be. Not what Remington used. You might post your question on the IAA forum. Those guys there know everything related to ammunition of all kinds, and it is by far the most likely source for a correct answer. You do not need to be a paying member to ask questions on the forum, just like here.

I was thinking REMINGTON?
Thanks for the suggestion.
Cute cat.

Not sure what the round is supposed to be, but it's a keychain the TSA will confiscate if you try to fly. They're keeping us safe, dontcha know...

 

[press-1-for-english]

Oh yes. I had a rather uncomfortable encounter with the TSA a few years back over a small pocket knife I forgot was in the bottom of my backpack....and I hear they were also considering P-38 can openers as weapons for some time.

Maybe look up a 44-40 win/rem in the Euro line of ammo?

The rimless is the killer, for data in my US of A data books.

 

[press-1-for-english]

Will do, thanks Nevada Ed.

It has similar dimensions to the 458 SOCOM but the bullet diameter should be .458".

 

[Rule3]

How about a picture of the headstamp?

 

[rockquarry]

.420 is the diameter of the bullet/projectile.

Did you measure with a caliper or a micrometer?

 

[NewLiberty]

It kind of has the aesthetics of a Wildey Magnum round. There was a .41 Wildey Magnum, but I'm having trouble finding case dimensions for it.

Many of those early "key chain" cartridges, especially during the Viet Nam war era when they became popular, were made specifically for that purpose and only superficially resemble real cartridges. I suspect that is what this is.

The .45 headstamp obviously does not agree with the measured diameter of the bullet!
