ABs were designed by Nosler to perform the same as Partitions, except they have a polytip which makes themmore aerodynamic. They are designed to open relatively quickly, lose about 35%, and penetrate. Test, by others, have proven that the PT penetrates a little more because the AB opens a little more. I prefer hunting bullets to match bullets because they were designed for hunting! Others disagree. capt david /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif
