3 inch hot shells?
When did 3 inch shot gun shells come into use? I am trying to determine the age of a shotgun. Sgt. Ron
Well it all depends you would be better off using the mfg. and serial number but I figure you would do so if you could.
Three inch shells were more or less common with brass hulled shells than the 2 3/4 so three inch was in use before 2 3/4.
Winchester offered 12 gauge 3" magnum in 1935.
410's in 3" started in the 1920's or there about.
