This is my all time favorite shot placement. I have NEVER had deer run more than 10 -15 yards if this shot is properly placed. I line up the verticle reticle with the deer's front leg and then line up the horizontal reticle right at the mid point of the deers shoulder. If I'm taking a 300+ yard shot I simply aim high on the shoulder, same result. This shot is only taken under ideal conditions for me personally, the deer must be perfectly broadside. In any other situation,I aim center mass.

I personally don't like a spine shot for 2 reasons: 1 - it's a small target, if you aim too high then you miss, 2- I love backstraps too much
