So, I have 2 dillon SL900 machines, and all three gauge conversions for them, and the 20 gauge is driving me up the wall! No matter how slow I go on the handle, it throws a couple pieces of shot out from somewhere, and I am not able to determine if it is coming out of the shell the shot was just dropped into, or if it is there is somewhere else the shot is hangin up and I am just not aware of it. ( the two or three occasional pellets come out of nowhere so fast that I cannot tell exactly where they are coming from besides the general location of the shot drop tube/shell area.). I could probably even tell what the hell is going on if they had designed these damn things so you could see inside the press, but no... They made it off of a 650 frame with the huge bar right in the front, and you can see nothing that happens on the platform from the front. I love the performance of these things when they do work correctly, but I cannot get this 20 gauge to quit spitting shot out. Has anyone had similar problems? Or should I just smash these damn things?
