So I recently bought a used mk 1 AMP annealer and used it for the first time today. Out of a group of 100 pieces of brass about 10 of them came out with these spots of various sizes on them. Is this normal? Something I need to be concerned about? I just wanna make sure I didn’t by a defective used unit or if I need to contact AMP about it? For reference this is hornady 6 GT brass using the AMP suggested 48 standard setting
