Vitals sit low and forward behind a shield of gristle; 1,000 ft·lb with a well-built bullet is the benchmark. Floor used: 1,000 ft·lb at impact plus the bullet's published expansion velocity. Orange = a target or varmint bullet (construction, not energy); red = never carries the energy. Sources: backfire.tv.
