Was at a local sporting goods dealer this PM. In the display case there was this green, paper, UMC #3 shot-shell. It is approx. the diameter of a half dollar coin. Can anyone tell me what gauge. I have a collection of cartridges, shots-shells, boxes and antique reloading tools that I display in a shadow box in my den. This shot-shell, fired BTW, has my interest.
Thanks for any information. NTG

8 gauge , or maybe a 4-bore for a punt gun?

Much larger than an eight gauge. Punt gun shell maybe.

What was the headstamp on this shot shell? I ask because I am pretty sure UMC made a 3 gauge shot shell.

The head stamp is Remington over the UMC with the No 3 at 6 oclock, bottom, of the shell. MTG

It is a 3 gauge or 3 bore then.

Much thanks ZW. I am in the process of attempting to buy this fired shell for my collection. I have many old shotshells that make up my waterfowl/shell collection.
I must say, I @m somewhat concerned when it comes time to pass them on. There are no waterfowlers in my extended family to carry on. MTG
