New and need some help

Pictures?

 

And you're most welcome!
Thank yous can be lacking here sometimes.

 

Agree that it is a 30mm Aden projectile, apparently the target-practice variety. It will have some inert filler to make it match weight and CG of the other types with energetic fillers. In the ammunition business the complete cartridge is known as 30mm x 113B, because the cartridge case is 113mm long and is belted (B) near the base.

 

Come to think of it, wife's biz has a few different flavors of those in stock:

Thanks springfld.arsenal. Any idea what metal the tip is and how old it is? It looks a little older than the links you posted.

 

If you google it you should see a pic or two. Sorry, I'm having trouble posting pics from my iPhone at the moment.

 

Tip, aka fuze, is always aluminum on this type. As far as I can recall the Aden/30mm x 113B round has been in service since about 1950's. WWII German Luftwaffe was the first group to use 30mm aircraft cannon on a large scale and it worked too well, unfortunately for Allied forces. So many of those countries copied the guns and the ammo, making minor changes. Most fired/recovered target practice projectiles have been battered and buried for some time, making those look older. Wife's rounds are new and unfired, the way collectors like them. They are US cartridge cases, made of green-anodized aluminum, to minimize weight in the Cobra attack helicopter. The US gun is the M230, which moves the bolt via electric motor and a motorcycle chain, not relying on gas from a fired round like the Aden gun does.

 

Wow! Thanks so much. That was extremely helpful.
