Antler restrictions do work. I'm from east TX and the size and quantity of bigger bucks are obviously noticeable since the rule came into place 20 years ago. Most bucks are busted up so bad come November, it will make you want to become a annual early season bow hunter just to kill a nice buck with all of it's tines and beams still in tact. I see excuses why not to introduce the idea, like lengthy rifle seasons hurt deer heard quality and there's less big bucks, or it just doesn't work topics. East Texas has a lengthy rifle season and it definitely hasn't hurt the numbers or quality. Genetics can help, but age always helps when it comes to a mature heard ultimately creating a bigger challenge. Older bucks can be harder to kill and sometimes keep getting older after that 3 to 4 year old illusive behavior and stealthy patterns. Older buck heards mean more rewards in the deer hunter's world.
