You "ground down" the die, why? Which type of Lee crimp die do you have? The seater/crimper die that comes with the 3 die set, OR the factory crimp die,(FCD)? Is it that the die bottomed out on the shell plate without producing a crimp? It may be a crimp die made for the 10 mm auto, then it would need to be shortened. If it was the FCD, then you just ruined it.

You must produce enough crimp to dig the end of the case into the bullet slightly to prevent the bullet from being seated deeper when the bullet strikes the feed ramp. Especially if you are near top pressure, then you reduce combustion space by seating the bullet deeper,KABOOM!

The factory crimp die from lee is the best investment you can make for loading strainght walled handgun ammo.
