TPWD was doing Helio control work on coyotes and they chose TT steel shot, the buffered high speed waterfowl load. I think they have now gone to various heavy shot loads but still use larger shot like BB and upwards. Many of the land owners have a no wounding clause in their release forms. I think TPWD has been fairly successful. Not so on hogs even with thousands taken there is no difference and the costs were extremely high.
