Bullet / Cartridge ID Needed

[Sooper Dave]

I found this bullet in a rural area where there was a lot of maneuvers for WWII. I do not know if this is something that would have been used then or not. I have never seen a cartridge like this before. It is about 2.5" in length and the lead is close to .30 caliber. It has a full metal jacket and it has been fired but the bullet just barley moved out from the casing. I can make out some of the letters on the rim MKII AIPA S3 8 ?? I showed a guy at work that reloads and shoots a lot, and it has him stumped as well. I only know common rounds of ammunition, so I need help from the experts. Thanks, David

I posted this on another forum and a guy IDed it as a British MKII Artillery Shell Primer with a link to this site http://www.municion.org/Estopin/Estopin.htm down towards the bottom of the page is a picture that looks the same, but someone as stuck a bullet in the case of the one I found to make it look like a complete cartridge. Here is another site on fuses and primers http://nigelef.tripod.com/ammo.htm It is awesome to dig up artifacts that you have no clue of, and have to do the research to learn about it.

The bullet doesn't look right in it. That threw us off, I was looking at rifle cartridges. I couldn't find anything even close to that rim. But even if the bullet wasn't forced in it, we would probably still think rifle cartridge. lol
Cool find!
