My friend and I are having a discussion/disagreement on deer reaction when hit well in the boiler room with a high powered rifle, in this case a 7mm rem mag. The story goes he was hunting last year and from a good rest shot at a deer at 100 yds broadside. The deer walked off into the woods, a few minutes later another deer ran to the same spot and he shot it in the same spot he shot the first one and it dropped in it's tracks. He is convinced it is his scope changing zero. While I concede it is entirely possible for his scope to be defective, it is also possible he hit the first deer perfectly and it just didn't die right away. He doesn't believe this to be possible. I have shot many, many deer with everything from a 450 marlin, to a 7 mm rem ultra mag and I have shot the heart and both lungs out and seen them walk off like they weren't touched only to pile up 100 - 200 yds away! I once shot a doe at 30 yds broadside with a 12 ga 1-3/16 oz slug Hollow point, blowing the heart and lungs to mush. The deer ran 100yds down hill and 50 yds up the next hill before dyeing ! When I dressed the deer is didn't have a drop of blood in it! Please agree or argue if you wish.
