The first few times i have tumbled my cast 00 buckshot they came out great. Shiny and smooth just like if you were to buy new pellets from hornady. however the last couple times ive been doing it they arent coming out like what they were. They are coming out rough and dull with the texture of raw cast iron. as far as i can tell im not doing anything differently than the times it was coming out good. Im using graphite pencil leads when tumbling. The first time it came out rough i guessed that it was because of moisture or humidity, however the attempt i just made now im certain was completely dry and not very humid. I keep getting upload failed when trying to add images to the post so heres an imgur link of the pellets instead https://imgur.com/a/PIlngFv the pellets on the right are the ones im having problems with and the ones on the left are the ones that came out good. anyone have any ideas on how i can resolve this?
