I am going to sit down and write a letter or two, and I think if we all did we could get this overturned. Many states allow suppressor use for game animals, and Texas is behind the curve. If you don't have a suppressor, you could have a .223 can for around $700 with the tax stamp paid––they aren't too expensive. Below is my reasoning, which can be a good start for a letter.
If you have ever heard 5.56 (.223) or .308 suppressed, you know it is not overly quiet. You wouldn't gain an unfair advantage, where the animals just stand there like nothing happened. I hunt feral hogs with suppressors, and out of a 5.56/.308 they react just as with an unsuppressed gun, but the effect on my hearing isn't as severe. There are sub sonic rounds that are more quiet, but not many folks would use them for hunting due to the reduced range from the low velocity rounds. If they did, it would be more akin to bow hunting, which is legal anyway––both are close range and make little sound.
What you would gain is the purpose of the suppressors, hearing protection! I have always hunted with no hearing protection (ear plugs, etc) so I can hear what is going on around me. Hearing loss is cumulative, and over the years you will start to gain a ringing in your ears and eventually hearing loss. Furthermore, I have guns I want to use to hunt game, but they have a muzzle brake permanently attached to accommodate a suppressor. Without the suppressor the brake is way to loud to shoot without hearing protection, ruling it out for hunting game animals.
Maybe someone could help me with who needs to be contacted. I am assuming it would be a director or high up in TPWD. That is who would make these rules, correct? Chime in if you know, also to say if you agree/disagree and why. You are entitled to do as you wish obviously, but I am going to write a letter to voice my opinion either way. This isn't out of reach, as many states already allow it. A few I know of from a thread in the suppressor forum are AR, WI, MO, PA, VA, MI.
ETA: Let's get the ball rolling. I made an
online petition to start building some momentum. You can sign anonymously if you wish. Thanks for the support, and spread the petition around!
