Has anyone ever heard of the "protective laquer coating" on the 5.7 ammo?I was told that a vibratory cleaner should not be used and only a sonic cleaner and simple green or similar should be used. I have never heard of this,however I am very new to the 5.7x28(although not new to reloading)BTW I am having a blast with the ps90 5.7x28 cartridge!
