Weatherby Ammo uses Norma brass and is loaded by Norma. It is loaded hotter then most factory ammo. Some produce velocities that a handloader cannot sometimes match and sometimes they don't. The components are A+ in this ammo line. When you factor in that they have Norma brass that is 2x of most brass then the differences don't seem that great. There is a dealer in my state that stocks a lot of it in all the weatherby calibers andit is not that much more then Federal Premium or Winchester Supreme.
