Last week I cast some really nice looking boolits. I am a firm believer now in not fouling up my mold by smoking the cavities. I was admiring the beautiful fill out to the point where you could see all the milling detail. Then I took my fingernail and ran it up the smooth tapered side of the TC boolit. It turned bright and silvery. Then I took the boolit and polished it up real good on my pant leg and admired how shiny and silvery it was. I showed it to my wife and she remarked, "It looks like it's made of silver!" Indeed. I was thinking about how my shooting buddies would probably be jealous if I was shooting PB this pretty. The silver boolit on top of polished brass is truly a thing of beauty.
Well a week has gone by and my silvery boolit has been parked on my nightstand. I remembered it looking shinier last week. I took the boolit and rubbed the nose on my pant leg again and sure enough it shined up again. I guess the surface oxidized over the past 7 days. Is that why the shine dulled? Do any of you bother tumbling your boolits in some soft media so they get all shiny and silvery? If so, is there some coating that will prevent them from subsequently getting dull after polishing?
Pretty absurd question. But I'm sure I'll learn something from the replies. Thanks!
