I finally tried using the HF red and using my vibratory tumbler (bullets are in a freezer bag). It coated decently enough, but certainly not up to electro gun perfection.
Accuracy seemed decent enough but I couldn't verify as the wind and cold was absurd today.
I have a couple issues. Everyone says they don't get any leading with PC but my 45acp barrel had what appeared to be (plastic?) smears in the first inch. They scrubbed out with a brass brush with some effort. I also noticed some sort of large flakes spitting out of the chamber.
Am I doing something wrong? These are baked at 375 for 20 minutes.
