Will a weatherby 300 mag fire any other ammo other than 300 weatherby? Will this shoot 300 win mag?

  fdchief6100,
  
  Welcome to the Gunbroker Forums!
  
  Yes, you can fire .300 H&H ammunition in the .300 Weatherby chamber and you will get cases that look like and are the .300 Weatherby since the H&H is the original parent case.
  
  No, I wouldn't fire .300 Winchester Magnum in the .300 Weatherby chamber. The headspace would still be on the belt but the rest case would lack support and alignment, not to mention the bullet jump to the throat. The brass would eject looking like a straight case with a partial Weatherby shoulder. The neck on the Winchester case is thicker also.
  
  Best.
