My father-in-law recently bought a used Uberti revolver. I have only had a chance to glance so far. On the barrel it is marked 44 Mag. He took it out to shoot and bought a box of 44 Mag. He called me and said when he put the cartridge in the cylinder about 1/2 in was sticking out of the back of the cylinder. So I had him double check to make sure it says 44 Mag and it did. The guy he got it from said he never fired the gun for whatever reason. Upon further discussion he told me the guy had given him a box of 44-40 shells with the gun. I am not familiar with this cartridge. I am just assuming here, is the projectile of the 44-40 a .40 cal projectile? I am not quite sure the model of the revolver but in my OUTDATED gun guide it could be an Uberti Cattleman? In my guide there were no 44 mags listed but there was a 44-40. I searched the Internet and found in 2010 they started producing the Cattleman in 44 Mag. The gun is blued with a case hardened frame and wood grips. Any ideas of what this could be? I also know there will be requests for photos so I will try to get those ASAP.
