Cooey model 84 20g, which shells

[Campbery]

I have a cooey model 84 in 20g, serial 0094###, on the firearm it says full choke but doesn't list what shells I can use in the firearm. Would this be chambered for 2.5"? Can I use 2.75" or 3" shells? Heard there is a serial # database I could look up the specs. Thanks

No there is no serial number data base. Yes you can use 2 1/2" or 2 3/4". As far as 3" you will have to measure trhe chamber. But if it is just the straight Cooey model 84 and not the Winchester/Cooey, it is most likely a 2 3/4" chamber.

thanks, pretty sure it's not a Winchester Cooey
