I have a old revolver that says pat. May 22 1917. On the barrel it says
FOR >38 L Colt<CTGS
38 S&W Special
Wondering what it will shoot.
I bought a box of 38 long colt 158 grain ammo. But wasn't sure if it shot smokeless powder
"it is at least THEORETICALLY designed for use with smokeless powder, since that caliber was commonly sold only as smokeless ammunition within just a few years of its introduction in 1899. "
I have no idea who the customers were or how much was sold, but the .38 S&W Special remained available in factory BP loadings until the mid-1930s with approximately the same ballistics as standard smokeless loads.
