the other resistance to 270 ever going anywhere is, look at the barrel twist in those millions of old rifles. Its really only the newer guns and that is IF they speed up the twist that new bullets could even be taken advantage of. a 270 that shoots 200 fps faster than a 270 win, doesn't sound like its really going to be a beneficial amounts when its not like your going to be using a 270 as a 6-800 yard gun.
I have shot the Hornady 145gr ELD-X quite a bit out to 800 yards in a 1:10 twist 270 WCF barrel. So I do not understand your 600-800 yard statement. Combo is perfectly capable at 600-800 yards. Took an antelope and mule deer with that combo. It worked great, but caused a lot of meat loss.
The more I read on the 6.8 Western, the more I like it.
