crimping 9mm cases
 
I have a Lee Pro 1000 reloader. I'm reloading 9mm lugar rounds. Do you have to crimp 9mm . I tried adjusting my seater die but don't seem to get a crimp.It is a Lee die. what do you guys think.

Yes you should crimp them. they get a taper crimp that is not as noticeable as a roll crimp like on a revolver cartridge.

To adjust you should take a UNLOADED and sized case run the press ram to the top of the stroke. Now screw the die down until you feel it contact with the case mouth now take 1/2 turn more. Run a test round and keep at it. If you have problems call the manufacture of the die they will be able to talk you threw it better than we can.

Taper crimping should be done as a separate operation. On a 4 station press, station 3 is for bullet seating, station 4 is for taper crimping.

9MM crimp??
 
:rolleyes::)Two must have tools for me for 9MM+.45ACP, are Lee Factory Crimp Die,and overall cartridge case guage. Both avail. from Midway. I load on a Dillon 550,with Dillon dies, and run all loads through the Lee Factory Crimp die as a last step. All loads are then checked with the o/a case guage. You'll find that 9 brass shot through a Glock, will have expanded bases, that only the Lee FCD will resize,after loads are assembled. The die has a carbide ring at the base that will help Glock fired, and IMO all 9MM/.45ACP loads. The o/a case guage takes the place of a barrel to check for fit of re-loaded round. Good luck, and have fun
