Looking for Load Data suggestions for CamPro 38/357, 158gr, FCP, TC and N320

Hi,

Looking for good starting and maximum load data for CamPro Bullets - .38 special and.357 magnum, 158gr, FCP, TC with Vihtavuori N320 powder.
I don't find any perfect match on Vihtavuori website: https://www.vihtavuori.com/reloading-data/handgun-reloading/?cartridge=41
As per CamPro website they are suggesting 3.2 starting and 3.9 max, which sounds too low. Case will not fill even half. https://www.campro.ca/images/-38.357.MAG.158.TC_-_38.SPL.158_gr.pdf

Please suggest. Thanks in advance.

N320 is a very fast burning powder for 357. You need a slower burning powder for true magnum loads. N120 to N150 range.

I would suggest you follow the data provided by campro. Note the 3.2-3.9 grains of N320 is for .38 spl. loads, they do not list N320 for .357 mag. loads.
