Here's my first Elk - in fact an Asian 'Maral' from Kazakhstan.
Shot with a 139gr Scenar from my 6.5 Creedmoor at ~590 yards.
The bullet went through the back of the heart and exited. The animal went 20 yards and collapsed.

As you can see he broke a top off falling about 150 yards down the hill (but I've got the pieces!).
