I like variety, and I use bullets from all of the major manufacturers except Speer. Some I pick for long range applications, some for woods hunting, and a couple for when I finally get to take that trip to Africa. For deer hunting, I want a bullet that expands rapidly at whatever range I'm hunting, so I choose a gun for that purpose. I don't believe that a mono bullet will reliably expand at 500 yards from my 308 when velocity has dropped to 1800 FPS , but a Hornady AMAX will. Likewise, a 150 gr Sierra GK from a 7X57 at 50 yards will make a devastating wound channel on a deer. The mono will do that also - for more than twice the price of a Sierra GK.
