The article shares data comparing it to the 450B, 458S, and 50B... Does that actually make sense? That comparison in this type of analysis doesn't really count to me if it's not in the same platform, might as well have compared it to a 45-70 in a levergun... I can't get a 45 Raptor in an AR-15, so why compare it to AR-15 heavy cartridges?
Does look like a fun cartridge though, but I'm not sure there's enough difference over a 308win in killing performance that I'd value another AR-10 upper.
