I target specific bucks in early season especially. I can really pattern specific bucks when they are still in bachelor groups particularly in early season, usually for the first week or2 until they all shed thier velvet at which point they break up and start doing their own thing. Its hot and lots of bugs but Ive had great luck hunting early season bucks that I have been glassing and patterning feeding routines. I can still hunt a specific buck after that but it gets more difficult as the big boys start going norcturnal where I hunt right after shedding.
