Sharps Arms New Model 1874 Old Reliable C. shotguns are known for having tight chambers. If the chamber is a bit undersize a gauge made to "industry" standards will not go in to the true depth of the chamber. Sometimes chambers were cut with slightly worn reamers giving a slight undersize chamber. The chamber body itself has a taper of about.

I usually repeat this a few times to insure I am getting a consistent reading, but you will be amazed how accurate this can be done. While still looking into the chamber simply slide the scale in until you observe the end coming flush with the shadow line & mark position of breech end with your thumb. May have to move the barrels around a little until it is distinct. Hold the barrels with muzzles toward a light source, not necessarily a concentrated one a window is great, while looking into the breech and the cone will be thrown in a shadow. A very good method I have found of measuring chambers without much outlay of cash, and is quite accurate enough for virtually any situation, is a common 6" flexible machinist's scale which you likely have. Fly in the ointment is nominal measurements often differ from actual ones in both chambers and shells. Prior to WW-II many companies had the practice of holding the chamber about 1/8 inch shorter than the shell for which it was intended. Today, theoretically when the crimp opens on the shell being fired the end would land at the junction of the chamber and cone. This is loosely based on the length of the "Fired" shell. Most got around to it by 1939 or 40.Ĭhamber depth is considered to be the distance between the breech end of the barrels and the joint between the chamber body itself and the forcing cone, which reduces down to bore diameter. The SAAMI meeting where it was suggested that our manufacturers start marking the chamber length on their guns was in 1937. I think the 1920s is as close as you are going to get.
