I went out calling for yotes early one evening during deer season this year. It was about 45 minutes till dark an I started using a fawn distress. About 2 minutes into it a piebald doe I had been hunting all season came runnin down the mountain and stopped at the edge of the field. Range was 347 yards according to my rangefinder. Seeing as how I had a doe tag, I made the appropriate adjustments on my scope, settled into a nice prone position and set the crosshairs on her white neck patch and touched off the shot. She fell like she was hit with a truck. I was shooting a rem 700 in .223 with 55 gr soft point ammo. Its all in knowing your gun and how far that bullet has to go.
