Technical question: 6.5 Grendel was developed because 6mm PPC wasn't considered satisfactory, (Note: both originate and can be made from 7.62x39 brass). So why is 6mm ARC so well recieved, when it's essentially 6mm PPC?
I just looked up Hodgdon reload data. For a SMK 107 gr bullet, running TAC powder at max charge
6mm PPC = 2650 fps
6mm ARC = 2549
The PPC is more powerful than the ARC, in that load data at least. What am I missing? Why go back to 6mm PPC/ARC as a general purpose round over 6.5 Grendel, if the Grendel was devopled to be the more effective general purpose round in the AR15 platform?
FWIW
6.5 Grendel 107 SMK ( they make a 6.5 dia version, which is a fantastic bullet btw)
= 2606 FPS
Again, this was intended as a Technical question more than a Ford vs Chevy perference question.
