I'm loading my first batch and I'm up to the expander die part. I'm loading .38 Special and using a 3 die set from Lee. I can't get any flare, I've followed directions carefully backing out the locking ring and the expander ball then screwing down the die till it touches then with a case inserted I screwed down the expander plug till it touched, then I kept 1/4 turns while I checked the case with a bullet. I screwed it all the way down and still no flare! and the bullet won't enter the case and I have no more room to screw down the plug. Am I doing something wrong?
