I will post this again. I purchased an 8lb jug of Superformance when it first became available. I used the listed load of 65 grains behind a 150 bullet in my 06. The load was accurate and was deadly on Mule Deer. This powder is do dense that 65 grains just comes up to the bottom of the neck. I wanted to use this in my 308 and 7WSM so I called Hodgdon and spoke with a tech named Mike. Mike stated that Superformance is very sensitive and to use only listed loads. He also told me that I could not use it in the 308 and 7 WSM. He went on to say that Hornady sells Superformance loads in non data listed calibers, because there are over 40 blends of Superformance and only one is available to us reloaders. The one that we can buy has the most uses.
