I have a Hornady progressive press, the dies, the shell plates, the bushings, a scale and caliper. I also already have common tools like screwdrivers, hammers, wrenches, etc. Can someone give me a list of other things that I will need (besides power, primer, slugs)? Links to webpages or other posts are welcome. It would be nice if you could add comments like "essential" or "will save a lot of time" or "makes things more convenient".
