The 264 Win...it was a dead years ago...I see Remington has chambered in their M700 SenderoII in 264 Win this year.....man what in the world are they smoking??? It's a dead horse....but hey anything can happen, the 280 Rem is more popular now as it ever was. It doesnt help that there is only one factory load avaiable, though I would assume Remington will bring 1 or 2 loading out. While the 264 Win might be a good cartridge you have to handload it to get better results and the truth is there are alot of folks that dont. Time will tell.....
