I have been using sts since it first came out many years ago and while there are some things you have to do and not do I am just not understanding some of these responses......
I have the Thumler's, I guess it's a model B...whichever one was supposed to be the correct one to tumble with sts pins. I have no experience with "cost effective" {translate to chinese schitt} tumblers, but if they are like the rest of the chinese schitt you buy these days you might want to just get a Thumler's and have one that will work for 20 years. At the end of the day, when you have spent enough to buy the Thumler's, you will still have chinese schitt.
I have never had an issue at all with running less than a full charge of brass, 20 or 200 the system works the same. I definitely do not find that you have to "size" down your tumbler, chinese or not, to clean a lesser amount of cases.
I have an RCBS separator and it works okay for doing a lot of cases, but I don't use it much any more. Not that it didn't work, but you still have to visually inspect every case for retained pins anyway {you will ruin a barrel if you don't}, so I find it just as easy to separate them by hand as I get them out of the tumbler. That way I've done my visual and did not remove a bunch of pins from the tumbler and have to loose more putting them back each time. Certainly for doing 25 at a time I would never bother with tumbling in a separator. What's it take??? 2 minutes???
As to the pins "beating the neck or mouth up" I am not seeing it. I hear people talk about it and maybe they use different pins than me. I have the ones sold by Midway. Speaking of which, they are magnetic enough to handle strays with a good magnet. I have also not had any issues with the necks being bare clean brass. Maybe some rifles are picky about this, tight chambers, etc., but a little lube on the bullet and it's been zero issues for me.
I don't sts clean every time I load and I don't care if my brass looks like jewelry as some ass clowns have suggested. I mainly use it on recently acquired once fired range brass to get it nice and clean to start with. i.e., no one would buy new Lapua or other high end brass and fire it once and sts clean it...
With the pins I use I definitely get 4 or 5 cases out of 200 with pins stuck pretty good in the flash holes. Maybe there is some new media that don't do this, but again, so you take a few seconds to knock them out?? You really have to do a visual on each case anyways or risk your barrel or decapping pin. The only other thing to really say is that you run the cases for the length of time it takes to get them clean enough for you and as to drying...I find that warming them up with a heat gun or hair dryer works fine, if you need to load right away blow them off with compressed air or rinse the water off in a vat of denatured alcohol. They will dry quickly. If you have time to wait for a dehydrator you probably ought to just wait until they air dry.
Somebody will be along to bawl about this post in 3....2....1......
