Just remember not all pins are made the same way and some have very sharp ends that can eat the surface of your brass.

I like my rotary case tumbler and using stainless steel pins, BUT less is more on tumbling times and use a magnifying glass to check and inspect your cases. These pins are bought from the cheapest bidders and not all pins are created equal. I have seen photos of short pins stuck in primer pockets and other damage so be careful.
