i shot the same one two weeks in a row. mysights where off on my bow and shot at the deer quartering away and cut him across the neck . tracked him for three hours and blood ran out . i knew something was up when my arrow only had blood on one blade and fletching. the next week he came back didnt know it was him till a doe came up and started licking his neck. when he turned i could see how it laid his skin open but didnt cut deep. he got back to almost same spot ,same position , this time my sights where right
