I'm new to reloading for the 300 WM. I have read that the military uses H1000 in their loads. I assume that is for velocity and temperature stability. While I have some H1000, I can't seem to locate any more. There is plenty of 7828 and 7828SSC available. How does this powder compare in terms of velocity and temperature stability? Bullets I'll be using are SMK 190, SMK 220, AMAX 208.
