After extensive tests with meplat sizes, radius and bands we decided upon a 67% meplat for caliber, proper radius, and three driving bands on the top and one driving band on the bottom as being the best all around design, with the small difference in spacing of the standard B&M bullet and the NE bullet. This was taken across the board to all calibers.
Having shot and worked with a great deal of copper and brass bullets over the last few years I did not wish to go back to the drawing board with a new design hollow point NonCon, whether brass or copper. I felt strongly about taking the standard BBW #13 Solid and putting a hollow cavity in that very same bullet. This would not only make it easier to manufacture, but it would be the exact same bearing surface, the same length bullet, just slightly lighter. For a Dangerous Game Bullet it is important that both the hollow point NonCon and the Solid have the same, or very close to the same POI (Point of Impact) at 50 yards, Dangerous Game range! Even though the NonCon HP is lighter, so far in every rifle, and every caliber I have worked with, the POI is the same for both Solid and NonCon. In fact, when loaded with the same load, the velocity is very close to being the same as well.
The BBW #13 Solid gives extremely consistent straight line penetration across the wide range of calibers and cartridges tested from 9.3 caliber up to and including .585 caliber. This is among one of the best nose profiles I have ever worked with. Below are a few samples of different BBW #13 Solids that have been tested. For more examples of these, and other solids please refer back to the various Terminal Performance pages.
