most bullets are .401. I have had all sorts of trouble reloading with .40sw. Using range brass lots of problems, using new starline none. The whole bullet bulge is normal.
Back to getting range brass to case...
Tried the Lee factory crimp die, did not work. Tried the undersize die, did not work, still a little glock bulge, bought the redding push through die and pray I can get range brass to behave itself.
