When I was in the Army Veterinary Corp from 68-71 down at Fort Bliss we used SC in various doses both in vein or directly into the heart with a bigger needle to put down all the stray dogs and cats that weren't claimed after seven days. It was the lousiest job I've ever had in my life and I had to do it as a part of my MOS under orders from the Officers in charge of the clinic! Here is a video of a kid that happens to be in PA shooting a doe with a Toxic and it was a clean pass through right in the boiler room and the deer went 400 yards. That does not impress me on a shot like that if it went more than 100 yards hit where it was, even though it was a tad low shot from the tree stand he was in! The blood trail was not good and the neighbor finally found it for the kid on the adjacent property!
