Agree. 308 is much shorter than 30-06Definitely not .308
Appears to be a Silver Tip bullet. No military rounds were ever loaded with those, so it appears to be a Military Case (WCC 45) reloaded with a commercial bullet.
Case ??????
Yeah that's all I found for 45 also. Don't think it's 30 tho. I think he got the 45 backwards also maybeI have WCC 45 headstamped .30 Carbine rounds.
