In 1956, the U.S. Air Force adopted the Cartridge, Caliber .38, Ball M41, a military variant of the .38 Special cartridge designed to conform to the rules of land warfare. The original .38 M41 ball cartridge used a 130-grain full-metal-jacketed bullet, and was loaded to an average pressure of only 13,000 pounds per square inch (90 MPa), giving a muzzle velocity of approximately 725 ft/s (221 m/s) from a 4-inch (100 mm) barrel.[18][19] This ammunition was intended to prolong the life of S&W M12 and Colt Aircrewman revolvers equipped with aluminum cylinders and frames, which were prone to stress fractures when fired with standard .38 ammunition.
hi Waveski and my fellow posters , why should I have problems with 125 jacket hollow points ??
I was thinking of loading hand full of Super Vel jacketed soft point bullets for testing.
hi , no bullets , not loaded rounds, remind me and I'll Post a picture
I've often wondered why the S&W aluminum K frame can't handle .38spl +p but the aluminum J frame can handle .357mag.
Because the .357 versions are not really aluminum, but Scandium.

ok, the 642 is aluminum framed, what is the secret with its aluminum that the model 12 didn't know about?
