grasshopper, you are free do dislike the .264
my point is that the .264 is not dead. it is more popular now than it was 10 years ago. (and yea, the naysayers called it "dead" then, too)
the OP wanted info about improving his M70, not a sales pitch about .270, 7mm, ect... this is not a cartridge popularity contest, it is a thread titled "Improving 264 Win mag"
you can pick ANY cartridge out there and make a case against it, but why?
ant264, you will be able to shoot lightweight bullets with the 1-8" or 1-8.5" twist. i have used this cartridge with 1-9", 1-8.5" and 1-8" twist, and the 8" and 8.5" twist will do it all. my Sendero SFII (1-9") will not shoot 142 SMKs, but would shoot 140 SMKs into 3" to 500 meters. my customs will do a little better than that with 142s.
but you gotta like 20 moa to 1K...
