Game Wardens that have issues with suppressors do not understand suppressors. The TPWD researched its records and the use of suppressors to hunt game animals is not a problem. The weapon of choice for illegal hunting is the crossbow. Listen to the archived audio of the last TPWD commissioner meeting. You can have a suppressor in your deer stand while hunting deer right now and able to use it to kill a HOG if one shows up. The problem now is that a Game Warden would think you might be hunting deer suppressed. He has to actually watch you shoot the deer at the exact moment you kill it if you shoot suppressed. It is not illegal to have a tagged deer in your truck and the suppressor on your rifle right now. I was shocked to hear this revelation. I think this change would take the unknown grey area away and make the Wardens job easier.
You are wrong about GW's not understanding suppressors. I know a whole bunch of them that have them and I doubt there are many that have never been around them. They suppress the sound that makes it harder or impossible to hear. With subsonic ammo especially they would never hear the shot. GW's make many, many good cases by hearing a shot and taking it from there. I imagine that most GW's will see it as making there job harder. For the record, 22's and 17's are the weapon of choice for most poachers not crossbows.
