they are getting bigger here, in the 80's we had upwards of 80 psm, bigger bucks weighed 110#, we have been really whacking them from mid 80's to late 90's, unlimited doe tags and such, now we get a 140-160#er pretty regular.
I brought up the bucks living to 13 in tx due to a book I read by Larry Weishun years ago, he was managing deer heards for ranchers, a guy called needing help, asked larry where all his old bucks were going, larry went by and checked the heard every buck appeared to Larry to be no more than 6.5 yo, so he shot a couple and had them aged, they were both 13, the ranch had a buck/doe ratio of 1 doe for every 2 bucks.
