Like most have stated...let the smaller Bucks walk and eventually you will get your chance at shooting a really nice Big Buck,try to be as scent free as possible when hunting,always try to better your hunting skills and it will pay off eventually.When I'm hunting for a nice size Buck I let the Doe's walk and they will draw/lure the Bucks in closer as the Rut season starts,as you get more patients you will be able to pass on more deer until you get the one you really want.
