He'll definately be bigger next year is he gets to hide through slug season. I hope that makes you feel better.

IMO a 100" buck is respectable. In some parts of the country he'd be considered a monster. I too have let deer pass and then thought I'd messed up but this is hunting. You may make up your mind to shoot him if he presents anouther shot and then decide to pass again. Ultimately only you can make that decision. With proper nutrition he'll be bigger next year if he gets the opportunity to grow but if there are no qdm rules in place on your hunting ground he's fair game.

If I were you I'd make up my mind weather or not to take him and if the shot is presented again be ready to act. Good luck and I hope he presents you with another shot wether or not you decide to shoot.
