help to identify a cartridge.

I was going through a box of stuff and I found a round of what I thought was 30-06 I don't own or have never owned a 30-06. So i thought this to be odd the case has no markings on it at all so I got out the caliper and the measurements I came up with don't add up to 30-06. I am wondering if it is a oddball round or a cheap made foreign round.

bullet length 1.10"
bullet dia. .308"
case length 2.483"
case dia @ base .465"
rim dia .469"
neck dia .374"
shoulder dia .433"
rim thickness .046"
overall length 3.305"

could you post the meaurement in inches ,most reloading data is in inches.
rough WAG you have wildcat round built on something like a 300 win mag or 8mm-06. a photo would help.

30/06 ---63.36mm ltg 8.36mm neck
308 norman mag 65 mm lt 8.65mm neck
300 win mag 66.55mm lt 8.63mm neck
8mm-06 63.36mm lt 8.99mm neck
As you see your in the ballpark .
