I've a quick question. What is the heaviest charge of black powder you've heard of being used in a .357 revolver cartridge? The original .38 Special was 21.5 gr. of black under a 158 gr. lead bullet. The GOEX chart shows 25 gr. for the same bullet in .357 brass. I THOUGHT I read an article about heavily compressed .357 loads with 30 gr. of black under a 158 gr. bullet.
