That range with a 30-06 is something I could teach my grandmother to do in an hour.
The question is can the shooter keep the crosshairs on the target as he squeezes the trigger. There are three factors that matter here. The shooters ability to breathe correctly while not pulling to the side as you squeeze the trigger and and not flinching at the blast or the anticipated blast. Also compensating for drop and wind. It’s Egyptian surplus ammo. I couldn’t find any online which is curious. Using wolf ammo ballistics info if either 145 grain or 180 grain the drop is 4 and 4.2 inches respectively. In a prone position firing at a stationary human sized target this is not a difficult shot for someone to make with minimal experience. The only factor would trigger control and your reaction to the anticipated blast.
