But who really uses factory ammo, anyway?
The component choices ABOUND in the .264! From 85gr varmint whackers all the way to 140 and 160gr elk slayers. No such thing as a "dead" cartridge when components are available!
If there was a bad thing about the .257 (there isn't) it would be that the bullets poop out at 120gr, even though there's plenty enough powder capacity (even in the 'bob) to go higher, and that's when the two cartridges would REALLY become indistinguishable. The .257 would gain in the bc's and sd's, and if that did happen, I'll guarantee you'd start seeing .257-.284's on the 1000 yard competition lines!
For that reason, alone, my pick is the .264. Flip a coin, or buy both!
