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
So, if we can eliminate gun crimes by passing laws against guns, why don't we pass laws against (recreational) drugs?
