I just had Hoser convert 1k pieces of brass for me. The service was fast and the brass is very nice. I will send him more and recommend him to anyone looking to convert their brass.
You can take the brass right out of the box I send it in and load it up. However I do recommend running them through a FL length resize die and maybe a quick twist with a deburr/chamfer tool. It is one of those cant hurt, might help things.
