Well my young daughter got her first deer today and with a 6.5 Grendel. It took more than one, but the first one was fatal the deer just didn't know it. Sadly we didn't prove whether the round was good past 200 yards. The first shot hit the on shoulder breaking it, angled through the lung, destroyed the liver and ended up somewhere in the paunch. That was a 100g NBT. 2nd shot was ~200 yards away and made soup of both lungs. 3rd shot from 80 yards and took most of the does head off when it lifted said head. In over 40 years of hunting I have seen deer do similar things with larger rounds.
