A 150" buck is big for around here but not necessarily huge. The biggest I have ever seen from stand would have gone somewhere around 160"-165" huge perfectly typical 10 pointer. Old son-of-a-gun too. You know how old bucks get those squinty eyes? Well his were barely open, LOL.
My dad saw one buck around here bigger. A monster typical 12 that he guestimated at 180". He would know. He killed a 186 3/8" non-typical on public land in 1985. Biggest deer I have ever seen... Him too for that matter.
In any given season I consider myself lucky to take a P&Y buck. I see a couple every year and usually at least one whopper, but seeing, getting a shot opportunity at, and harvesting are leaps and bounds apart
