Well first off, let me break this down into 2 different sub-topics:
1.) Ideally yes, well all want our bullets to strike through the heart so they die shortly thereafter, however we are all human and we all can't be "Bob Lee Swaggers (from the movie Shooter), it was also a 200 yard shot from someone elses rifle, the situation was my hunting partner and I pulled up and the hunting partner's friend said he saw the young buck and he gave me his rifle, I didn't ask questions because we didn't have time. I had never shot the rifle before, nor did I know if he had 100 grain .25-06 or 120 grain .25-06 bullets loaded up, I also didn't know what yardage his scope was zeroed to. So that was the hand I was dealt with 1 hour of shooting light left on a cold and extremely rainy afternoon, I unfolded the bi-pod, laid it on the hood of a car, and put the crosshairs 3 inches or so below it's back line and squeezed off a round from a foreign gun at 200 yards away.
2.) The second order of bussiness, why I didn't finish the deer off was a complex matter. I shot the deer on a friend's land, after the deer was shot it then ran and hopped a fence and laid down and rolled around on someone's else's property. The owner of that property, my luck, pulled up on his land right after I shot it and it crossed his fenceline. I knew the land-owner, good friend of my uncle, however he doesn't allow hunting on any of his properties. So I grinned and beared it so-to-speak and waited patiently for him to leave, then me and another person ran 200 something yards to the deer like rainbow six operatives and drug him back 200 something yards. I was stuck between a rock and a hard place, I shot the deer legally on a consenting land owner's property but my luck the deer decided to go onto someone elses land. Believe me, the day before a shot a deer and walked to it instantly and put a round in it's head and he died right then. To show my ethics, about 3 weeks ago I was walking back to my house, a silver pontiac sunfire passed me, right after that I noticed 2 deer running perpendicular to the car about 50 yards away, I thought to myself surely the driver will see the deer and slow down or stop. The deer following the first collided, it rolled off the top of the car and landed with a thud on the pavement. I asked the 2 people if they were okay. Then I put my hand on the deer's flank to check it. It kicked around and then attempted to stand up but it couldn't, I determined on the spot that the deer had broken either both of it's back legs or it's hips. I walked to the house which the collision happened literally right infront of, got my Masin-Nagent M38, put two 203 grain JSP 7.62x54R in the gun. Walked down and put 1 round into it's heart, and then the second into it's head. The deer spasmed for about 3-5 seconds and died. Me and the driver rolled the deer off the road. Then I went into the house and called the Judge of the town I live in (small town) which he is a family friend. The following morning a truck pulled up and 2 men from the county put the deer into the truck and drove away. I hope by this reply I have cleared myself so-to-speak and being a new member to this website I don't want to get off on the wrong foot.
