Just a word to the wise; the bullets that are handled (or processed) least, are almost always the bullets that will shoot best. That bullet is at its peak of accuracy potential when it comes out off the sizing die and into the collection bin beneath the press. Anything done after that, will degrade the base accuracy of that projectile. This includes inspection, polishing and final packaging. Sounds odd, but bullets ar actually pretty fragile. Any rough treatment, such as carelessly dumping them into a collecation barrel rather than carefully placing them, will likely cause concentrity problems in the finished product. Final polishing can be tough on them, as Bart explained earlier. Anything that came down to the range for me to use as standards in production testing, never saw the, inside of a tumbler, and were taken literally straight off the press with nothing further done to them.
We can talk about pointing an uniformity meplats in another thread, but suffice it to say, the same cautions apply, and that enhancment process can also work against you if not done properly. People like shiny, well-polished bullets, so the bullet makers polish them prior to packaging. But for years now, those shooters in the know have tried to get them to package bullets straight off the press, unpolished and still covered with the oil used in production.
