I cant tell from the pic, but the pin on the bottom of the machine looks bent. I was thinking about this yesterday wile I was sizing and seating gas checks on some 32 boolits that are half linotype effortlessly. Try sizing a undersized boolit so that your just cycling the machine with no sizing going on to see if the machine is binding up on it own. I size aged linotype boolits for my 44 with no trouble. Something is wrong.
