You may want to re-think posting illegal hunting activities on the Internet. Hunting with a suppressor is illegal in Texas. Go here and go to Page 54. It's clearly stated as being "NOT LEGAL".

As another poster already has stated, in Texas they are non game animals and can be hunting by any means you can think of. You can use machine guns, night vision, thermal spotlight anything you can think of. Additionally they are one of 2 animals that I know of that you can leave the where they lie without cleaning them. Many hunting outfits only use nightvision and suppressors for hogs. Same with coyotes in Texas, any means you want to. Suppressors are very very very popular for hogs in Texas, most serious hunters I know have them or have on ordered.
