Chad,
My 10 pt I shot 18 years ago (in Ontario)dressed out at 218 lbs with a hoof length of just over 4 inches.
I think this one you found belongs to a very nice size deer & I personally would not be ashamed to even sit a stand to even get a look at what it looks like.
Who knows, if you spend the rest of the season getting to know what this guy is doing, then at the start of next season he will be even bigger (hopefully) & you will have an idea of the pattern he is using.

Good Luck
