Cast bullets being swaged when seated in 9mm case
I have a problem. If using a 9mm expander through die, it swages my cast bullets really small when seating. Down to .349 in some spots. I replaced the 9mm with the 38sw plug into my expander through die. 90% of the finished rounds crimped good but the remaining rounds I could move the bullet back and forth and rotate it inside the case. I couldn't pull it out by hand but it still wasn't crimped in there right. I am using the bullet seating and crimping die with no crimp being applied followed up by a Lee factory crimp die applying a medium crimp. I even see the crimp line in the bullet on the rounds I can rotate and move the bullet in and out by at least .020. I'm not sure if I need another brand of taper crimp or what I need to do to fix this
