Many people apparently still don't understand that even if a bullet will group in a certain twist, if it isn't "overstabilized" by a minimum of a 1.5 factor (1.0 is enough to remain point-on) then BC is reduced by up to 15%. Thus you may have a bullet with a listed BC of .450 but the functional BC can be as low as .380-something.
BC isn't a hard and fast figure, and often another bullet designed to fully stabilize in a certain amount of twist but a lower listed BC may work just as well, because it retains all of of its BC from that twist.
One of the other reasons I suggested the possibility of the 95 Ballistic Tip is I know it's a sure-enough elk bullet, because the guy who designed it for Nosler killed several with it, including mature bulls.
But whatever.
