Dang man, congrats on the tags!
Offrange Oryx is TOUGH, you just have to get lucky and be in the right place at the right time.
Your choice of rifle and scope are both good choices. Don't discount Tikka T3's. I have 3 of them and a buddy has one also. They are all tack drivers. I don't really like their rings, but they work and the action is smooth as glass.
Ignore Stinky on the Leupold comments. They are made in the USA and have a fantastic warranty. If you're planning on dialing your hold get a tactical or go big and get a Nightforce or Valdada. The Leupold VX3 w/B&C Recicle works good. Nikon scopes are also nice and I like the one Ziess I have, but it has zero advantage over a top end Leupold.
Good luck on your hunts!!
Oh yea... 300 Win/WSM, 7MM Rem mag, .270 WSM, are all good calibers with plenty of energy out to 500 yds and beyond.
Since you're considering the ultra mag, why not get a 338 RUM?
