The Kirst Cartridge Konverter™ for the 1851 and 1861 Colt Navy revolvers.
.38 Long Colt -Six Shot: The .36 caliber percussion revolver barrel has a bore diameter of .375 inches. Today’s .38 caliber cartridges are loaded with .357-inch diameter bullets. To attain accuracy with a modern .38 caliber cartridge, in your reproduction Navy revolver, you must shoot soft lead .38 Special, hollow base wad cutter, .38 Colt hollow base or .38 Colt healed ammunition. The soft lead hollow base bullet will “bump up” to the .375-inch bore diameter and shoot very accurately.
The chambers will actually accept .38 Special hollow base wad cutter cartridges; however the cylinder is too short and is not intended for use of the standard .38 Special cartridge.
The cylinder has been made this way so that the shooter can use commercially loaded hollow base, soft lead bulleted ammunition, it is not intended for the standard .38 Special cartridge.
The Kirst Konverter for .44 caliber 1851 Colt Navy, reproduction revolvers.
.45 Schofield/.45 Long Colt -Five Shot: The current Pietta reproduction 1851 Navy revolver in .44 caliber accepts the same Kirst Konverter as is used in the Pietta made 1860 Army revolver. Since the .44 caliber Cap & Ball barrel has the same bore dimensions as a present day .45 centerfire caliber, the Kirst Konverter will simply convert these guns to a 5 shot .45 Schofield cartridge/.45 Long Colt. It will also accommodate the .45 Long Colt cartridge if the bullet is seated slightly deeper. The ammunition must be loaded with lead bullets and a low-pressure, powder charge that DOES NOT EXCEED 1000 FEET PER SECOND VELOCITY!
.44 and .45 caliber cylinders must NEVER BE INSTALLED IN A .36 CALIBER REVOLVER!
(The SAAMI specification for overall length, for the .45 Long Colt, is 1.600 inch. The longest overall length that 1851 Pietta cylinder in .45 caliber will accept is 1.58 inch) |
