Do you realize that if you are actually aiming where the heart is, and if you go over the heart by much more than a few inches, you hit the spine. After that there is a lot of no mans land thats nothing but a wound. If that same higher hit is placed a bit farther back it takes the top of the lungs and you have a kill?
I wished more folks knew how tiny the area is where the heart lies. Its a small target.
And since I can't control the deer's reaction (here in TX anyway they are uncanny about ducking) If I hit within an inch of where I was aiming I"ve had total success. Its not uncommon not to hit at all OR even hit the opposite side here.
Just went against my advice since I was sure where the crosshair was when the rifle went off. And it was a chip shot and I saw the deer start to stumble before he dissappeared. End result? Followed up in a bottom about 10 minutes later. Found he crossed a deep creek with blood in the water and all along the bank. He just kept going. I suspect he knew we were after him and I assumed that after a bit I'd find him laying there..... Anyway 3 hours later we jump him and find he has a broken lower leg. With all the blood he lost we MIGHT have recovered him if we left him lay. In any case I should have just waited some even with a rifle shot. Went back to find a limb that deflected and probably opened the bullet about 6 feet from him. Probably zero penetration too...... Waiting is best again....
