Guess I'm the lone ranger on this one, but they did very well in my huntsman with loose t7 I had less crud ring and could load a 2nd shot easily were i couldn't not with w209 had very good groups, but I had good groups as well with the w209. But I could see were it could be a problem with the pellets but then again I never could get the best accuracy with pellets with w209 either, thats why I went to loose powder. They do as advertized in my gun I dont have to strain anything loading a fast follow up shot. I always try to wet patch between shots and sight in that way but if you wound or need that fast follow shot they help. If I was using any other powder other than T7 I probobly wouldn't use them. But the short barreled huntsman can use the boost the fast burning T7 can give it for velocity. I recomend them but only if your using T7. :money:
