All the new cartridges seem like good ones, I especially like the 6MM Creed but what will it do for me a 308 won't? A 9 pound 308 doesn't kick hard enough to snivel about and I have never had a hard time getting a 308 to shoot. I am in the hem and haw stage of picking a cartridge for my next barrel going on a Remington SA. And why shouldn't I build a 7-08?
