Take some youth hunters out. I know alot of young hunters who would love the chance to shoot huge 6 pointers. Your options to improve the herd sucks but if you are going to try to kill off that unwanted trait both doe and buck will need to be thinned out. Maybe you could lease your land out thus receive money to improve your herd while allowing others to harvest a deer or better yet allow young hunters an opportunity to hunt these deer you don't want around. Where are you from/ where is this happening?
