My thoughts... cleaning the brass won't do anything for easing the primer crimp... the crimp is there plain and simple. Nor will it (cleaning with SS pins) do anything for the size of the flash hole... the flash/burn from the primer ignition is not as such it is fouling the flash hole significantly enough to cause these problems. If your decapping pins are getting stick in the flash hole, see about using smaller/different pins.

I can't recall the last time I had stick pins in flash holes but I've heard about it.

I use RCBS pins and load WCC (both NATO and non-NATO marked), LC (both NATO and non-NATO marked), Rem, Federal, Hornady, Winchester, Speer, IMI, and others with NO stuck pin issues.


I don't think wet tumbling is worth the time nor the mess. 2 hours in my Hornady vibratory case cleaner gives excellent "new" looking results.
