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!).
My goal, and regret, whilst living in Kazakhstan for 2 1/2 years. I just needed to head home whenever I could get away.
