Good info guys. Thanks... Any of you guys try magpro with a 150gr. partition? If so, how temp stable is that line of powder?? The Nosler reloading manual lists magpro as a good powder to use in the 270 with the 150gr. bullets.. I know there for a while, all I could find was magpro, IMR 4350 and H1000. Trying to find H4350 and H4831 was impossible, but now I'm seeing it on the shelves again.
