OK, I will be the one outside the norm on this a bit. I have had really good success getting newbies to shoot with "high" power rifles by starting them at 25 yards off the bench. You want to eliminate as many outside variables as possible to school the shooter on all the right steps before, during and after pulling the trigger. If the shooter can't shoot well at 25 it won't get better at 100 or farther and causes frustration to the newbie. You can walk them thru on really good shooting postures and technique at the 25 that translate well out to 200 since an 30-06 with most factory will be on at 25 and pretty close to on at 200. Getting a newbie success builds confidence and focus along with belief you know WTH you are talking about. I'd even throw in some paper animals to give some additional practice of kill zones etc. getting them use to finding the "spot" before pulling the trigger is many ways half the battle to groom a newbie. The rifle will be easier for them to handle at 25, see instant success (or failure) which goes to coaching and the target is really clear for them to see. I also use impact targets since newbies seem to really like seeing color splats and they are easy to see at 25. The other advantage of using 25 is getting some ballistics thrown into the training since you are explaining line of sight crossings at 25 and 200 which helps a lot in their visualization of how a bullet flies downrange.
Once you have built the confidence and success you then move out to 200 re-enforcing the ballistic portion of the training of the 2 line of sight crossings that a bullet undergoes in flight. The shooter now has reasonable confidence on how to hold etc for a 200 yd shot.
Can't overlook you can set way more targets at 25 than 200 since you have a very short walk....us old folks need to take that into consideration as well.
