It shouldn' t be impossible to get both. Everything in life is a balance, if I have a bullet like Sierra that gets .5" groups at 100 yards, but won' t stay together in a barrel burner gun, I would rather have a bullet that gets 1.5" groups but holds together.

For deer, it don' t matter if its coreloks, or a rock out the end of a gun.
But for elk or an expensive hunt that is a once on a lifetime, I would think hard.
Lots of choices out there. Should be able to find something.
