Hi my Mec collet on the 9000E will mushroom gun clubs about 1-3/100 which I don’t mind too much but same rate on my federal papers and I can’t stand wasting those so I went and got one of the best forum members here to sell me a Mec case conditioner that I’ll run the papers through first. But I tried running AAHS the other day and it mushroomed 5 out of 7 so I stopped and switched to GCs. I run a bore brush through it and grease it. When I had a 9000gn I’d feel the stroke hit a bump and I’d know it’s the hull not dropping on the collet and I could force it down but not on the Automate it just plows through them. Maybe I have a bad collet? I never took one of those apart but maybe I should try.
