I have fired .38 Special mid-range wadcutters (148 grain bullet / 760 FPS) cartridges in Colt 1892 series revolver without any problems. The hollow-base bullet expands to fit in the oversized bore and since the bullet is flush with the front of the case they will fit the chambers without any problems. This particular loading is similar to the .38 Long Colt in bullet weight, chamber pressure, and velocity.
THIS IS THE ONLY .38 SPECIAL LOAD THAT I WOUND FIRE IN ONE OF THOSE OLD COLTS, AND SINCE I CANNOT EXAMINE THE CONDITION OF ANOTHER PERSON'S REVOLVER I TAKE NO RESPONSIBILITY FOR THOSE THAT MAY TRY IT.
