I'm not sure I'm buying the data after looking at the list multiple times. Things that were also scarce are there, which makes me think that isn't why 270 is missing and 6.8 is there. I'd want to know the scale of the data reported and see sources before assuming this wasn't an advert for 6.8 and 6.5prc. I NEVER see 6.8 where the vast majority of folks buy guns and ammo. But it jumped 7 mag and is trailing on 308? Eh...
