They are constructed the same. That said, Nosler and all companies frequently change the construction of bullets, such as jacket thickness, etc.without telling anyone. I've found these fly and perform exactly like the BTs. Advantages of the BTs are no point deformations, potential ballistic advantages due to the more streamlined shape. I do know that the .284 120 grain Ballistic Tips of fairly recent manufacture have rather thick jackets, more so that earlier ones.
Since the thread is back...
