Measurements would be amazing.

The biggun isn't the standard 20mm some know and love -

or it would  be more proportioned on the same scale as .50 browning.

I'm gonna go with 30mm AWSHIT.

That sounds extremely similar to some of the WWII foreign HMG rounds used in aircraft guns...  13 and 15mm stuff.


But NOBODY shoots those anymore.  Half the ammo was mini-HE, the other half was AP or T...

The case paint visible in your picture would allude it to be a 20mm case...
9/26/2012 6:56:57 AM EDT

Looks nothing like my 20mm rounds




Case length is 4.258"
Base is .875"

That settles it.

When I win the lottery, I'm buying a motherfuckin' 20mm rifle.  Absolutely badass.



Only $13,000, and it shoots Hamiltons.

I have one with those exact measurements. It's a case from a M103 20mm shell according to the printing on the side.

It's US 20x102. 102mm is actually 4.015. I'm betting the extra 35 thousandths is how much it grew after fireing.

Just for the brainiacs there is more than one type of 20mm

I'm not calling a dupe or anything, but is anyone else having a Deja Vu moment with this thread? Holy fuck this is weird. I swear I read this exact thread last week.

It's a 20mm Vulcan, the other pics of the 20mm that were posted is a 20mm Oerlikon
 



my comparison...white tipped is the Vulcan and the one on the right of it is the Oerlikon

I'm also going with the 20mm.

Here's a pic of a 6.8spc, next to a 50bmg, next to a 20mm.
