The Steyr Pro Hunter is a piece of junk...short barreled (which reduces accuracy), crappy trigger...and not a good hunting rifle, especially for a newbie! I know, I had one and it was as accurate as throwing rocks at the target!
As a few others have suggested I would also recommend 2 rifles...a plinker 22 (like the Savage Model 93) and a hunting rifle.
If I had to give up all but one of my guns and keep one for all my hunting needs...I'd have to say I'd keep the .308 or .270...really hard decision. But both calibers are easy to find ammo for relatively in-expensive too (well by today's standards). Both calibers will allow you the flexibility of hunting hogs or deer and have modest recoil.
Seeing how it is your first rifle, I suggest something less crappy than the Steyr Pro Hunter and less expensive than the Sako and a little more durable and friendly handling...
Rifles...there are many options for relatively inexpensive highly accurate (sub-MOA) off the shelf rifles that can be had for under say $600. Look at the Tikka T-3, the Browning A-Bold, Savage (model 116, 110, etc.), the Weatherby Vanguard Sub-MOA, or the Remington 700's. All will produce sub-MOA accuracy, have adjustable triggers, and all cost under $600 new and are available in most big-box stores off the shelf.
