I was using my NOE 452-277-RF mold for the first time today. I’m guessing it was either the dry mold Frankford arsenal release spray I used on the HP pins and must have caught a little over spray in the mold and or grease from not wiping out the brand new mold? I’ve had similar results from the Frankford release spray on similar boolits I’ve casted. I thought my boolits were frosted at first and turned down the temp on my lee 4-20 until I don’t get fill out...but they still looked the same.
Any other ideas what might have caused this. I used COWW and pure 50/50 along with 2% pewter. I plan on PCing and GC my boolits . The little divots always get filled in by PC coating and not noticeable after baking it on.
It seems in the past if I wipe out my mold I get smooth boolits again if I remember.
