I don't own one or need one.
It is a hard hitting round.
I guess it all depends are you needs, better become a expert at picking brass at the range- those babies 'round here are costly and you won't run them 20 times like you might with a 7x57. The cases are as much a consumable as the bullets and powder. 2 or 3 times might be it.
Maybe, the shop will pitch in a couple of boxes of Weatherby ammo- or maybe they can't find any either.
Just pulling your chain but there is a bit of truth in it.Cheers
