Shotgun Chamber Length Question

[u/Zealousideal-Let8726]

This might be a silly question, but my uncle recently gave me this shotgun and I'm not sure if it can take both 2 3/4" shells and 3" shells or only 2 3/4" shells.

The gun is:

Cooey Model 840 12GA 2 3/4" - 3 full choke Winchester proof steel Made in Canada by Winchester

I've attached a picture.

Thank you all!

Yes, as per the stamping, this is a 3" chambered gun.

A lot of these shotguns were made around the time when 3" chambers were becoming more common, so many were stamped that they could shoot 2 3/4" shotshells as well to not confuse the Average Joe who might think he couldn't if they only stamped 3" on there.

Thank you all for your help!! 😊😊 I’m a new PAL licensee and I look forward to trying out both 2 3/4” and 3” shells on this shotgun!

Also throw some 1" down there, and 2.25" OH THE OPTIONS YOULL HAVE A BLAST
