I'm not much of a reloader but I gotta ask.....
Exactly what category are we talking about here. Varmints, antelope/ deer, elk/ moose, bears, dangerous game, target shooting, 600 yard bench rest etc....
Each has a variety of excellent bullets that are designed for a specific purpose. We would probably find that most serious guys use all of them for different loads and different uses. but, what is their favorite?
I think you just answered your own question right here. There is no favorite bullet that will do it all the best.
