I wouldn't recommend a .300 Win Mag. to anyone starting out in a precision rifle just because of the associated costs or shorter barrel life which are, of course, all valid points.
The substantial difference in recoil alone would be a deterrent for most people, especially if they plan on shooting more than 20 rounds per range session. A relatively inexperienced shooter would develop a detrimental flinch almost immediately and would no doubt affect his shooting technique.
As you stated, Rotaxpower, you want a rifle to shoot at 600+ m. Well, the .300 Winny is overkill in that area and your needs would be better suited to the .308 Win.
Get the .308 Win. and shoot the Hell out of it. By the time you wear out the barrel (if in fact you would ever do so) you would have enough experience to make a step-up worth your while.
