Matt,

I’m not aware of any published research about the percent to total antler growth by specific dates.  July 4^th would be approximately the midpoint of the antler growth season throughout most of the whitetails’ range.  However, I’ve noticed some bucks seem to express a high percentage of their growth early while others appear to stack on the inches during the last portion of July.

This is much like humans.  For example, I was the second tallest kid in my fifth grade class. However, I wasn’t noticeably tall compared to other males in my high school class.  I gained height early while others grew later in their development cycle.

I’ve looked at 20,000+ Reconyx images during the past few weeks and I’d say some bucks have expressed ½ or more of their antler growth and others haven’t grown enough that I can identify them yet.  Unless I see something really unusual, I reserve estimating a buck’s antler potential until August.

Growing Deer together,

Grant
