I use 5 pins in my setup. First pin at 15yrds and one at every 10yrds up. First of last season durring practice I put my bottom pin on the deer targets belly and where ever the deers back crossed thru the sight window, I moved that point to the kill zone (if a pin was at its back, I used that pin, if it was between two pins, I put one above and one below) and it has been DEAD ON everywhere I've move the target. A deer is apx. 20 to 26 inches from belly to back and six deer this year have been the results of using this method. I draw, focus on the deer, pin spot the belly (with the bottom pin), locate the killer pin, and cut loose. Does this make sense to anyone else?
