Deer-class rules of thumb; a slightly bigger animal than a whitetail. Legal: CO: 1,000 ft·lb at 100 yd. 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: chuckhawks.com, www.petersenshunting.com.
