No2 shotshell case?


Legit case? (not mine, from web)



At least a funny and truthfull headstamp!


Love it!
Looks like it has been fired.


Would expect duck to be plural

Doubt a legit Punt Gun round


There was always a guy at the Lincoln, NE gun show that had one, but didn’t want to sell it. He always said it was a joke.


Obviously not a period-correct cartridge but maybe a machinists-shed-made one for actual use in a punt gun?
