Sadly it was Weatherby that made factory rifles and loaded most of the available factory ammo. Premium price for the rifle and about as darn much for 20 rds or Weatherby brand ammo.. If Winchester, Remington, or Ruger chambered it, it may have picked up more of a following.
Oh well, us that have em know its merits, and if there truly was a candidate for 1 rifle for deer sized and up game in North America, im of the opinion that the 338-06 would be high on the list of candidates.
