According to this article by Zak Smith, a 140gr .260 carries 87% of the energy of a 190gr .300win mag at 1000yds.


IMO the only reason .308 is popular is due to its military use. 6mm, 6.5mm, and 7mm are all ballistically superior to the 7.62mm.
I've been curious about 6.5 Lapua for some time now. I wonder if an AR-10 pattern rifle could be made to work in it....
