Thanks, BD, your comments are very helpful! Your experience pretty much fits my expectations of this cartidge. I found a stock (4 boxes) of the Weatherby ammo at a very good price languishing in a small shop. I bought it (though it's loaded with Hornady bullets) because it gives me some brass to start with and something to use on paper. I think Hornady makes great traditional cup/core bullets. I use them in my 6.5X55, .30-06 and .30-30 rifles. However, like you, I don't think they're manufactured with the stresses of magnum velocities in mind, so I'm not surprised by your ruined meat stories.
Frankly, I haven't even purchased a scope for the lavish gift I received. In due time. In the meantime, I picked up some 140 gr. triple shock Barnes bullets. When the time comes, I'll be curious to see if this rifle likes it or not. Seems to me like that bullet ought to make a great do everything load. Like you suggest, the time-proven Nosler partitions are always an option as well. Guess I'm still childish enough to derive great pleasure from dreaming about future adventures with a new toy...and dreaming is free (smile).
