So i put arrow in a young buck today at 4pm broadside at 25 yards right above his shoulder. I saw it run off 70 yards in an open field wight he arrow stuck in him. I shoot a PSE Rally with a 60lb draw. I thought this was going to be my first bow kill. This is my second year hunting and first year hunting with a bow. I end up searching for blood an hour later after i hit him. I can't find any blood anywhere. I follow where i last saw him last. I found the arrow on the ground after he ran through some thick brush. 20 yards after i found the arrow, i found a tiny bit of blood. the blood trail was only about 30 yards long with little blood drips. Im guess i hit too much bone.The arrow had 6inchs of blood on it. Can anybody help me out with why i didn't find blood till 100 yards later?
