Heaviest Black Powder .357 Load

[Owen49]

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.

If you compress to hard you get a cigarette burn ie. a solid that burns from the end.
If you want more power go for 4f powder.

I've used 19.5 gr. to 23gr, lightly compress both with a over powder wad.Both loads with Black Powder and Remington primers(which I'm not really sure makes a difference when using BP.)

If you want more power go for 4f powder. And with a compressed 'brick' of powder with FFFFg ... the foul will be harder than a woodpecker's beak!
