I have a RCBS trimmer that is all od a sudden not holding the case tight and when I start cranking the brass case spins also. Ive tightened all the screws and its still doing it. I have to hold the brass and then turn with the other hand. Has anyone else had this happen. Yes I have the right shell holder on it too. It does it in 270, 30-06, 300 ultra, 22-250. Oh and its not seeming to align straight to the mouth either.
