I believe that we hear of these issues with the 6.5, because it is the new toy on the block. Very seldom do we hear other issues with other calibers, and I'm sure they are happening, but go without the shooters bringing them to our attention.
My son is dealing with his 6.5, and he will ship it to Weatherby, and I'm sure they will make it right one way or another. It sucks to have a new toy, and not be able to use it because something is jacked up. I did tell him to be extra patient with Weatherby because of the move.
