What size shells can I shoot in a break action Cooey 84?

[lord-humungous]

It doesn't say on the barrel. I was Ok shooting 2.75", can I shoot 3' shells in this gun or should I stick to the 2.75" shells.

 

[Levi Garrett]

would say no, but must be somewhere on the rx...

You should NEVER attempt to fire ammunition that is different from the type that your firearm is chambered for. Firing 3" shells in a 2 3/4" chamber is a VERY bad idea and can cause you to have a very bad day.

I should clarify, there is no stamp on the barrel. Does anyone know what these guns were chambered to shoot?

I have one that's a 3". It's a Cooey 840 (winchester) tho so I dunno. Apparently they do have 3" and 2.75" models tho. Measure the chamber.

the length is that of a fired shell.
2.75" is the length of an open shell, so the 3" is actually 2.75" (give or take) unfired. It'll fit, but it ain't the best to shoot.

I was under the impression that the 84 was 2 3/4, while the 840 was 3-inch...

This is correct!! The cooey 84's only handle a 2 3/4 in shell.

When in doubt go to your local smith and have them tell you.

ONLY shoot the short ones UNLESS the barrel is stamped for the longer ones. There were no 3" shells until after WW II but there were plenty of firearms produced prior to then.

 

[Pickupman]

my buddy has an 84 thats stamped 2 3/4 and 3,best bet is the gun smith

 

[Grouse Man]

It HAS to be stamped on the barrel somewhere.
