The 30-06 has killed more elk than all other calibers combined! So not only is it adequate, but it is more than adequate out to 400 yards. In fact the next time I hunt elk with a rifle, I will likely take my '06 and I also own a 7mm mag and a 338 win mag. You have PLENTY of gun.
Also, ammo makes a difference. Hornady makes some ammo called superformance that ups the power of the '06 to that of a 300 win mag. Look at that ammo with the 165 gr or 180 gr interbond or GMX bullets. I like the 165 gr for power and trajectory.
