Where is over here? The U.S. probably had more cheap revolvers made in .38 S&W than any other country. Over the years they have been used with every .38 S&W cartridge made. Other than more recoil the 38 SUPER POLICE had no more pressure than the standard 146 grain load which was loaded to higher velocity.

Without knowing which powder, the grain load means nothing. Bullseye is an extremely fast burning powder while Unique is a slower burning powder. With the 146 grain bullet 2.0 grains of Bullseye has a velocity of 710 fps while 3.0 grains of Unique is only 590 fps.

Someone had run out of things to worry about if they thought a low power pistol load would split a pistol barrel.
