I had good success removing factory lube from some Missouri bullets I was given. First used very hot water which took most of the lube off. The lube floated to the top and was easily skimmed.
Then gently swirled them in regular paint thinner. Thinner got what remained, it showed a light blue tint when done.
Another wash in warm water, let them dry and was done. PCed them the next day with great success.
The paint thinner was less harsh and less expensive than acetone.
Prior to removing lube these bullets shot well but leaded my bore pretty bad. After trying a few different loads I decided they were just too small and gave up. Rather than melt them down thought I’d try removing lube. Two coats of PC and they shot well with no leading.
