Headstamp id

Metal detecting old gun range. Found a pistol bullet (I think .45 acp) with the headstamp WCC 41. Could I please have some info about it?

Good Morning Freddo55.
First of all, this is no bullet but a spent case. It was made in 1941 by the Western Cartridge Company (Olin), East Alton, IL . 45ACP? Probably but the length of the case gives the certainty.
Case length of this kind is about .898.

Thank you very much for the information, it is much appreciated. The measurements do confirm that it is a .45 acp.

Thanks again, Hamish.
