I also reload .410 (and 12 gauge) on a MEC 600jr. You have all the stuff but the reloading done by hand is a $#@!bersome process and I'd get bored with it real quickly!
The Mec loaders are everywhere. I bought mine new but my buddy Steve bought his 12 gauge MEC on Ebay for 1/2 of what I paid. The .410 loader is pretty expensive at $200 new but it makes shells VERY quickly. The thing I like best is that I can leave it set up, dump some powder in it when I need shells and crank out what I need in short order.
From reading the title I was trying to image what handtools one would put in a shotgun shell. lol
If you intend to do any 00, make sure you include some smaller shot to make side wall pressure. That pressure is what makes it work right with hand tool loading. I'm not sure the MEC is setup to handle anything other than shot.
