Going green will mean testing with new bullets, not what is on the market already. There has been enough experimenting with solid copper designs to show that a .25 G7 BC is about the limit with a 5 cal long bullet with a 3 cal ogive in any caliber and all calibers can produce the same BCs. The weights will be apx 115-125gr.
IMO which doesn't mean jack, the 6.35 is too light and the 7mms are too heavy to meet the weight reduction goals. A green 6.5 bullet with a .25 BC will be as long as the 139 Lapua but needs a hybrid ogive along with the other features above.
You're right, they will say yes that looks good but we're sticking with the 5.56 and 308 because it has worked for 50 years.
