Several ways to slice that cat---
Once we start stretching magwells, strengthening bolts, and so on, where do we stop?
If, for example, we allow COAL of 2.4" for the Grendel, would we not have to do the same for the 6.8 SPC? Or, for that matter, combine the two and go with a longer COAL 6.5 mm version of the SPC, say 2.5"?
Of course, we wouldn't be putting that cartridge into AR15 frames.
How do we know, for the purposes of discussion, when we have a design that works?
7mm should not be a player because high BC bullets have weights so close to those of .308" dia bullets as to not offer an advantage.
