I was getting leading with .356 BBI’s when I used a FCD. It was sizing them down to .354”

the FCD is fine for plated and jacketed but not coated
I order the stuff on Amazon called Grrrip. It's almost identical to Progrip but a tiny bit cheaper and it's to my house next day usually.
I tried Liquid grip and didn't like it. Wound up giving it all to a buddy
