  The Berger 230 grain Target Hybrid is the highest BC bullet available for .30 caliber.  Berger’s introduction of the Hybrid design has been very successful at achieving it's goals of length tolerance (less sensitivity to seating depth) and high BC.  This particular bullet is the heaviest .30 caliber bullet made by Berger and shares many design proportions with the 7mm 180 grain Hybrid and 338 caliber 300 grain Hybrid.

  For many years, there has been a shortage of well designed heavy bullets in .30 caliber.  In fact, the article: "What's Wrong With .30 Caliber?" was written about this very problem; which is a shortage of well designed heavy bullets for .30 caliber.  This 230 grain bullet as well as it's little brother (the 215 grain Berger Hybrid) have filled the gap well.

  At first glance, the sheer weight of this bullet may cause many shooters to assume it's only suited to large volume cases like the 300 Winchester Magnum and larger.  However for long range competition, especially Palma and F-TR, this bullet can do a lot to enhance wind performance if the shooter can manage the recoil.  It doesn't matter that the bullet starts out under 2500 fps and has 40 MOA of drop; the name of the game is wind, and this bullet will minimize wind deflection better than lighter bullets, even at a depressed MV.

  Stability is good from the common 1:10" twist.
