    i would shoot the winmag barrel till the throat barrel and muzzle are worn out then rebarrel it with the ultra mag.

    Unless there is a shortage of 338 WM ammo, I see no real benefit to the swap. Both should work fine in the magnum length action. I agree to shoot the WM til the barrel is shot out and then consider the swap.

    Unless you reload and really REALLY want the small jump in velocity I'd leave the 338WM barrel on it until it starts to degrade in accuracy. If the 338 WM barrel demonstrates poor accuracy it's a different story. How does it shoot?
