Looks to be pretty fat for this time of year and I can see a decent sized brisket in the last photo, so I'm going to go with 4.5 to 5.5. But aging deer this time is year is hard for me, so I'd take all that with a grain of salt. Hopefully some of the more expert guys will weigh in for you. Good luck, he's a nice looking deer.
