Actually, this is more of a question about ballistic coefficient of bullets.
How much does this really matter? And do manufacturers skew the numbers just to make a sale?

My gun seems to prefer 180 grain bullets, I don't roll my own, and am leaning towards the Winchester Premium Accubond or Silvertip. Mainly because they have excellent BC numbers.
I usually buy premium rounds for hunting andwill shoot them when sighting in.Iprefer thefeatures of rapid controlled expansion over penetration or muzzle velocity.
