Has anyone loaded cast bullets with IMR-4831 in the 308 win? I have a couple pounds left over from when I had a 270 and would like to use it up, I have a 177gr 185gr bullet currently to use, I do plan at some point to get a 200gr 311299 mold. What I am looking for is load data on it, and what sort of velocity did you get from the load you used?
