So one day I was just thinking about life... And this idea spark struck me! What if... I took a factory Hornady 162gr SST Superformance in 7RM. I used the same powder charge of Superformance but instead tipped the load with a 162gr A-Max.. Has this been done before? Or anything similiar? Who has done development using Superformance before? Is it all as good as Hornady claims?
