I shot a whitetail at 50yrds from a stand with a .284, 120gr SP with open sights in So. TX, when I shot I saw some debris fly on the other side of the deer, I though SH!t, I shot under it, when I got to where he was standing there was a huge amount of blood, a few feet away I found the bottom of it's heart, about 1" thick and 2" around, this was in the brush country 75 miles south of San Antonio, visibility into the brush was almost nill, very thick, I tracked the trail into the brush, found a small mesquite tree that it had run into, covered with blood, looked for it for more than 30 minutes, was ready to call my Dad on the radio for help, then I spotted it's tail, it had drug itself unfer a thorn thicket and all that was sticking out was the tail, it was more than 50 yrds from where it had been shot, I drug it out and gutted it, the heart was completely gone, pretty much vaporized, the exit wound was close to 2" around, so with no heart it went 50 yrds into very heavy cover,
In NE I have seen a large whitetail shot in the shoulder and the hip, and still go more than 2 miles before it layed down, after a couple of hrs of looking with several people we found it and it jumped up and started to take off again, and was finally put down with a running shot to the spiine, it's amazing how far they can go even severely injured,
