We had Dr. Craig Harper in town a couple of weeks ago speaking to a group of 60 of us. He said that 75% of antler growth is completed by July 1st, 90% growth completed by August 1st. Hope that helps? BC
My observation has been that deer are very individual in how they grow. I've seen some nearly done by the end of June and others that really blow up in July and one mature buck once that did a lot of growing in August.
This is an interesting topic. July 1st is 7 days away. I'm thinking these smaller bucks haven't got serious about putting on the bone. The vids were taken June 10th & 19th....I pulled the cards yesterday. This is northern MI.
