I know at least one monster buck that was only about half grown by this date three years ago. We saw him on the 4th and he was just barely turning up, but by the 24th he was split on all forks and pretty well finished by the first part of August. Yet down the road a bit there was a nice non-typical that was almost totally done by the 4th of July. We saw both bucks on the archery hunt. The non-typical didn't look much different, but the monster 4 point had 30 guys sitting in his bed on opening day and we never saw him again. He was the biggest velvet buck I have ever seen, but he didn't put on the growth until late in the summer!
So who knows?
