Dogger, sure isn't anything at all wrong with an ADL.
As with most any "off the shelf rifle", to get best accuracy you'll probably need to do a little work, like bedding the stock, get some trigger work done, etc.
A 30-06 with a standard barrel (ADL, BDL, M77, M70 or most any brand or model) should be able to hold at least an 1 1/2", 3 to 5 shot group at 100 yards when the wind is laid down, using quality ammo.
For Deer I sure like the Federal Premiun 165gr GameKing load. My Vanguard shoots 3/4 inch 5 shot groups with this load. Also that GameKing bullet really performs on Deer. For heavier game I move up the the Federal Premium with 180gr Nosler Partitions. The group does open up with these heavier bullets, but is still under 1 1/2".
You can't beat your scope choice of Leupold VXII 3x9 "for the money", of course this is just MHO.
I'm sure you'll enjoy your 30-06 ADL. Calibers & rifles don't hang around as many years as these have unless they perform. k
