I would like some advice since I am new to loading this caliber. I have 1 unopened can each of 2400, Blue dot and 300-MP. I would like to trade one can for some 357 Mag brass and would like to know which powder you all think is most suited. Presently I have wadcutters 148 gr, 125 gr RNFP, and 158 gr TLRN. None of them are gas checked. I will likely shoot the magnums at higher (1100-1300 fps) velocity (hopefully I can make it work w/o the checks) as I have 38 spcl loads I enjoy for the lighter shooting.
Sooo, one can has to go. What do you think?
Thanks for your opinions.
