I avoid anything "Clays" except for shotshell. It is just too easy to confuse it with other "Clays". I used to load Clays in 45acp with good results and then I got ahold of some Titegroup; it outperformed the Clays and was more economical. I sold my 40 and don't reload it anymore, so I didn't try any TG loads in the 40, but am pretty certain that it will work well. When I did reload 40sw, I used W231 and it worked very well in my subC-XD40. What are you shooting?
