Hahaha,
A case prep station is very helpful. There are a few out there.
I have an ultrasonic cleaner and a SS tumbler. I sonic clean mostly. It's not better but it's not worse.
Case and bullet comparator. Definitely a must.
Case lube. A few different methods on that.
A mitutoyo caliper. Its solid plus a fun word to say.
I learned a ton on here and was able to go out and not fuck things up. Lots of knowledge on here. You will see a trend with many products and methods. Once again take good notes, mental/physical.
Funny, I'd have said all that to the T!
You need a good manual, probably the Lyman for that but one specific to your powder or bullet brand is also good, then get Loadbooks for each caliber you plan to load; they have data from several sources in one book for one particular cartridge. The book has all the basics you need to know plus data.
I got my Mitutoyo caliper at a pawn shop like 30 years ago and the damn thing had to be 30 years old then at least! It's still dead on. I got a cheap Franklin set and it's not nearly as consistent but works well enough and I keep the Hornady shit clamped to it.
The ultrasonic cleaner is nice, especially for small amounts of brass and you can use it for suppressor and weapons cleaning too. Hornady makes one, I got 500 free bullets with it so it wasn't too bad. A cheap dry tumbler is good to have too.
I second the Chargemaster, that singular item has helped more than anything IMO. I'd like a second one so I could go faster. I use like an auto trickler with BMG brass, throwing ~230gr. and letting it do the rest.
It's hard to say with the press. I have a 650 but I still use my old RCBS single stage for all kinds of odd jobs. The cheap little 505 scale I use now and again to test the Chargemaster. I don't really use any of the other stuff.
I really like the Wilson gauges, they're fast and easy to use. I also have the Hornady setup but still like the Wilson gauges.
I don't use the prep station anymore, I have an RCBS though. Once I switched to the Dillon auto trimmer I never looked back, that's probably the singular piece of equipment that really changed it all. Speaking of, you'll need a trimmer. A good one, preferably an automatic one and not a hand crank. Unless you aren't loading much, that manual shit gets old fast. The Dillon trimmer goes in the press but it sizes, trims and chamfers in one go, and expander mandrel opens the neck up and presto --done.
I do case lube, I sell it on here. Pure cosmetic grade lanolin emulsified in 99% alcohol at an 8:1 ratio. You can cut it with 100% more alcohol and it'll still be stronger than anything else sold. It'll last you forever that way and uncut it'll size military BMG brass without any effort. Nobody sells the stuff nearly as strong or as cheap. So I can help with that.
Good luck!
