OK, now I am really confused. The 6mm Grinch is from the 6.5 Grendel which is from the 6mm PPC which is from the .220 Russian, which is from the 7.62X39. The 6.5 Grendel was developed for the AR15 and the straight case on the Grinch is made for designed for accuracy in a bolt gun -- why is the Grendel the parent case for the Grinch?
