Winchesters recommendations is not to reduce this powder on magnum pistol loads. ( ,357 and .44 mag. )
I am loading for a .458 SOCOM and WW296 is the only powder that I have that seems appropiate. Is it safe to ladder some loads looking for best accuracy and function? The SOCOM is not a SAAMI cartridge so loading is " own your own ".
I would appreciate anyone with loads for a 350 gtain and WW296 in the .458 SOCOM.
