Have the same rifle, and been shooting it for about 6 months. Not sure what would fit comfortably for you, but found that I like a taller mount (~1.5" to scope center). Started out with BKL cantilever mount with riser block, but found zero's drifting by 2'. Other folks that use BKL have not had this drift issue, so maybe just a fluke in my case. Eventually made my own mount/ring combination, if your interested contact me PM about details.
Other things I found about the rifle. Trigger needed work, had lots of creep initially, not the usual crisp Anschutz feel. Recently when re-installing the barreled action into the stock and torque per factory spec, it "mushed". The barreled action is now pillar bedded. Don't get me wrong, I really like the rifle, and once worked thru these little problems its a great little rifle.
As for ammo, found the Lapua Midas (or Master) L works pretty good. Eley Match also works well (but has an occasional flyer).
