I just read an article in the NRA magazine about Hornady's 6 ARC based pretty much on either the Grendel or PPC. I guess PPC has a 40 degree shoulder although I can't recall, and the Grendel is blown forward from the PPC, right?
But I just have to ask, why chunk back 3 hundredths in the ARC? Is a 6 Gren throated for 103 grainers seated Stoner mag length totally inaccurate or something? Or was this a feeding issue where the ogive curve was behind the case mouth? I really don't think "powder space" was why....
