I have the Wideland Veil in 300 Win and my buddy has the Wideland Veil in 300 WSM. We both love our rifles. The 300 Win is limited by the magazine length, so I can't load 212 ELD-X or 215 Bergers, but the 200 ELD-X works well. 300 Win has also been easier to find ammo for.
My suggestion: buy ammo first, then rifle that chambers it.
If you can get 200+ rounds of Win or WSM, that will make your decision for you. Save the brass and send it to Custom Reloads of Dallas for a new load.
