I think 19 downed deer from a stand is doable too. I think weather a deer goes down right away or not depends on shot placement - more than calibre.
Personally, given a choice, I don't shoot for the shoulder - I don't like to 'blow up' the animal like that. I'll shoot right behind the elbow - right in the lungs. No meat damage and the animal will go down 8 out of 10 times. The other 2 times it may run a few yards.
yah - blowing up the shoulder will put them down. But, it's not the .270, 308, or 30-06 thats doing it - it's bullit energy hitting all that bone mass and the animal forced to absorb all that energy
