I recently found some old cast boolits (NOE 360-182 WFN) .... don't know where they came from. These were sized with gas checks installed then it appears they were lubed with something like Alox. Needless to say the lube is sticky and the boolits are now pretty dirty.
Can these be cleaned in a vibratory brass polisher without harming them? I would like to powder coat them for my Rossi 92.
