Most ballistic mathematical models and hence tables or software takes for granted that one specific drag function correctly describes the drag and hence the flight characteristics of a bullet related to its ballistics coefficient. Those models do not differentiate between wadcutter, flat-based, spitzer, boat-tail, very-low-drag, etc. bullet types or shapes. They assume one invariable drag function as indicated by the published BC. Several different drag curve models optimized for several standard projectile shapes are however available.
The resulting drag curve models for several standard projectile shapes or types are referred to as the:
G1 or Ingalls (by far the most popular)
G7 (long 7.5° boat-tail, 10 calibers tangent ogive, preferred by some manufacturers for very-low-drag bullets)
In general the G1 model yields compariatively high BC values and is often used by the sporting ammunition industry.
Today, Berger Bullets operates several custom built machines that monitor pressure and reject bullets that are outside of required tolerances. These machines are more consistent than a hand press operation by using presses that provide accurately repeatable travel and speed. When combined with the highest-grade materials available we create a bullet that achieves the ultimate in consistency from box to box within a lot. Compare the results of this process to the mass produced bullets and you will find the reason why their bullets need to be sorted by accuracy minded shooters while Bergers do not.
The future of Berger Bullets and J4 Precision Jackets includes the further evolution of our process. We continue to build machines that run faster while maintaining and improving consistency. Our sights are set on being able to provide bullets to every shooter who cares about accuracy in a timely manner. There are going to be new introductions to our line including the addition of new calibers
