I've been reloading .223 Lake City once fired brass. This is how I prep cases:

1: Tumble cases for three hours in CV500 case vibrator with treated media

2: Inspect cases

3: Trim, and debur all cases

3: Deprime and resize with single stage press

4: Swage primer pocket with Dillon Super Swage 600

5: Clean and ream primer pocket with Lyman hand primer pocket ream

6: Inspect cases

7: Tumble case for one half hour in CV500 case vibrator to freshen the finish.

8: Lube cases with Dillon case lube

9: Load into the auto case feeder, and run through XL650

 

The problem is about every ten or so case. As I as pushing the handle foward I hear that cruch. I remove the case and sure enough the primer has been crushed. I then place the case into a container with with rem oil to soak. Is this normal, or is there something more that I need to do to these cases?
