Interesting about the dies potentially not working with the SR primer brass. I'm lazy and switching to Lapua brass with the SR seems like way too much work, especially when the Hornady brass seems to be working so well.
As for the magneto speed, it doesn't move the POI much with my heavy barreled .308, but it moves it a whole bunch with my 84M. A good 4-5" at 100 yds.
