Last fall as I was loading ammo for the upcoming seasons,I gave Hodgdons a call to see if I could use Superformance in my 7WSM. The tech I talked with (Mike) told me that I would not work and that there is over 40 blends of Superformance used by Hornady but only one is available to us reloaders. He was quick to caution me about following listed loads as this powder is very very sensitive! So all I loaded was 65 grains in a 30-06 behind a 150 CT BT. Took a nice 4 point buck in area 4 with this load.
