Has anyone out here tried H870 in the 7 mm Mash super. I have several pounds to use up and I'm just finishing the stock on my build so need to be thinking about load development. I also have lots of R 19 & 22 as well as H4831sc. Will be working with Hor
175 & 160 eldx as well as Nosler 175 partitions. Any assistance would be appreciated. Thank you. Feel free to pm me with your thoughts.
