It is shooting dang good and flat for me
Ok, so you are saying your weatherby is doing something else that nobodies can do?
Even giving some and saying your 180gr is flying at 3500fps, which would be almost undoable even with a 30-378 Weatherby and 5" high at 100, you might get 6 or 7" low at 500. And You would be flying 8.5" high at 250yards.
Man, you sure your ready to go hunting? Are you sure your actually firing the gun? Are you sure your actually going hunting? Why in the world would someone want to have thier scope set 5" high at 100 yards?
I doubt Nosler has anything to do with it. Sounds like many years of practice are in order.
