I have a old 183K 3in chamber. Can I shoot 2 1/2 in shells in this gun? I thought I could but then some friends said no and some said yes, now I am second guessing myself :? Any help appreciated
Typically the longer chambers are "backwards compatible" so to speak, so as long as you dont go any longer than 3" you should be fine. If you'd like a definitive answer, give the folks at Havlin Sales a call...
