You're still confused, or intentionally ignoring what you're being told.
It is impossible to make a .30-06 that has the same velocity with the same bullet as a .308 with the same weight and recoil. If the velocity is the same, the .30-06 will either have more recoil, or be heavier (to keep the recoil the same). That is the simple consequence of using a less efficient cartridge. There's no way around it - simple physics at work.
Oh, any you're not getting an extra 100y of effective range unless you're loading overpressure .30-06 or underpressure .308. The difference in velocity is much smaller than that.
