Novice query: does anyone have any experience reloading using Hornady Superformance powder in the Grendel? I am just starting out but I was thinking of trying to work up some loads with the new 123SSTs. I am concerned that there may be some reason (that I don't know) why this powder is not used in AR-15s? Sorry to be so ignorant but I appreciate the help.
