Found a oddity at the bench today.

[Detritus]

While making my latest batch of .45acp today. I came across an odd case, and wondered if anyone had see this before and/or could clear up what's going on with it.

• case is (except for head-stamp) visually indistinguishable from "normal" .45acp cases.
• Berdan primed (so unusable by me, anyway)
• Marked 11.25 x23("above" primer) 4FLB80("Below" primer) see attached pic
• 45acp metric specs are 11.43 ×23mm
• Large primer

the above noted discrepancy between the head stamp and official spec was what actually made me curious, if the markings had matched spec I'd have put it on the shelf as nothing more than a Berdan primed European made 45acp case. but now I'm wanting to know more

So Argentina marks/marked their 45acp ammo oddly (even for Metric markings)...
Good to know.

Detrius, to further complicate things:

Metric and English measurement have a 'ratio' number. One either divides (by the ratio) inches in thousandths to get millimeters or multiplies millimeters (by the ratio) to get inches in thousandths. However, they don't always come out even. Same idea applies to weight and so on.

Not all 'authorities' measure the same way. F'rinstance, the Brits measure bore diameter (for rifles anyway) from land to land, while the Americans measure groove to groove. That's why a .256" British rifle and a .264" U. S. rifle are both 6.5mm (like the Swede Mauser and Mannlicher rifles). And some 'authorities' tend to round off more casually than others. F'rinstance, the .26 Nosler cartridge is actually a .264" or 6.5mm bore. For that matter, why is a 8x57mm Mauser cartridge sometime called a 7.92mm Mauser?

Gotta be flexible.

Seems the '4' in 4FLB80 doesn't count. I'm assuming the 80 is the year of manufacture.

"...Argentina marks/marked their 45acp ammo oddly..." Yep. 11.25mm converts to .44". Mind you, 7.62mm does not convert to .308 either. It converts to the nominal bore diameter of .300". Don't even think about trying to figure out why cartridges are named what they are. It can give you an aneurysm.

Great photo, BTW. Don't think I've ever seen one of a headstamp that sharp. Well done!

Amazing what the cameras in our phones can do nowadays isn't it? that was taken with the camera in a Galaxy S7 Active, from just about the minimum distance it would focus. took 3 shots and that was the best.

Looks more like it was shot with a macro lens. I have an S7 Edge, and knew the camera was good, but no idea it was that good. Back to the topic, I am seeing headstamps from brass I pick up at the range that I've never seen before. Apparently, brass is made just about everywhere these days.

For posting on THR, I used to do close up pictures with 12 MP Olympus SP-600UZ digital camera but since LG C800 smart phone took such great pictures with built in zoom/macro, I now take all close up pictures I post on THR with LG Premier smart phone.
