LEJ headstamp on 4,6x30 case

Please, help me to identify the manufacturer of this 4,6x30 case
Thanks for any comments

Jagemann Technologies, Manitowac, WI
see the link for info.
They also have a JAG headstamp used thus far on their pistol ammunition (357 Sig, 9mm, 10mm, 45 acp, 40 S&W).

I wanted to clarify that the JAG headstamp has also been used on a few rifle cartridge casings as well, not exclusively just for pistol/revolver rounds.

Thank you very much!
