I also like my bullets to be shiny. Corn cob media with Flitz media additive.

Ever have problems with cold welding? I used to know a guy who annealed bullets, but he would apply an oil on the bullets after to prevent cold weld.
That sounds like bad ideas. Changing the metallurgy of the jacket material could alter how it upsets in random ways. Oil has potential contamination of your powder, inconsistent bullet neck tension. No thanks.
 
Have you personally witnessed cold weld? I haven't. I've only read about it on the forums. I've pulled bullets from milsurp cans made in the 70-80s. No cold weld. I recently pulled bullets from ammo I made 10yrs ago. No cold weld.
I have experienced cold weld in cartridges (bullets pulled to check) that sat for a number of years due to interest in new and flashy alternatives. Caused an over-pressure situation and a pierced primer. Kept in a cool and dry environment, as is necessary and required, didn't seem to be a preventative. I have since taken to using graphite neck brushing to prevent further problems.
