Judging from the muzzle of that buck I'd have to go with my original conclusion, 2.5 to 3.5 on the OUTSIDE. But he sure has one hell of a body on him already for a Pa buck. That buck will be a dominant one day soon for sure.

He better be a dominate buck this year because he ain't making it to next year if my arrow finds him.

Hope you get him, come season, that is one nice buck! And we don't eat the muzzle anyway?! That's a shooter, for both his rack and meat, i have a similar one on my property, that i hope to hunt. Good luck.
