by mid July they usually have most of their "main frame" grown. I doubt that deer will get much wider but his beams will grow longer as will his tines (his G-1s appear close to peak however). Their spread and beam "height" is pretty much done growing by the time their beams "make the curve" or start growing back inward. They just add on length too the points. I'd guess he'll grow into about a 16" 7ptr.

Mass always appears much larger while in velvet but that deer sure appears to carry that mass out everywhere for a buck that size!
