I got some 360 dw brass to load for my 357 mag handi rifle being it's one that has the extra chamber space for it. My main goal is to have the longer case length and getting bullets closer to the rifling as I am dealing with the long forcing cone issue and have not reamed it out. I have magnum powders for the hot loads that are listed for 360 dw but I have been all over the internet especially graybeards looking for lower velocity loads for cast bullets. I have a good bit of green dot,herco and small rifle primers and have always loaded 357 mag cases but would like to see if these lower pressure loads will become more accurate getting them closer to the rifling. Any reason I can't use 357 mag charges of herco,green dot in the 360 dw case to get cast bullet velocities?
