I have heard the same thing as everyone else throwing in their 2 cents. however, and I have no personal verification of this, I was told that if you take a bull in rut with bow and arrow, the nasty taste is virtually eliminated. The theory behind it is that while the rifle kills through sheer force and transferring the bullets energy to the bull, the arrow bleeds the bull of most of its "tainted" blood. This bleeding causes most of the toxins to exit the bull before it can taint the meat.

again, don't know if it is true, but that is what I heard.
