According to Hodgdon the 264Win mag will run 3000Fps at max safe pressure.
I would throw away a 264 Win Mag if 3000 fps was all you could get with a 139/140 grain bullet. Any decent 264 with a 24" or longer barrel will give 3150 - 3250 fps without excessive pressures. 3000 is a realistic max for the 6.5-06 using a 26" barrel. Expect about 50 - 60 fps less with the 24" tube. Eagleye.
