I have some. It works OK. The Winchester has a large hallow point and expands well out to 100 yards not to mention it is the most accurate subsonic I have ever run in my 10-22. The RWS is not bad and it is a HP as well. The worst subsonic I have ever shot is the Remington Subsonic, not the green tag match subsonic. Ely was good at one time, I don't know what happened to them. The pic I just posted with the two pigs I trapped were shot with a Ruger single six three screw with Winchester subsonic HP ammo.
