Congrats on the new machine. And welcome to the club!
Some further 550 tips....
• Nice that you bolted the press to a piece of plywood, but the first time you operate that you're going to find that it needs modification. The plywood is a great idea, but you'll need a much more substantial table to clamp to. And you'll need at least 3 clamps to hold the thing to the table. There's a lot of force involved and you'll find all this out for yourself very quickly. If that's your only table, then you may want to add weight to the table top, like several boxes of books! Just saying.
• BTW, stability-wise if you can't get the press/table combo to calm down, then order the Strong Mount. The SM allows you to set the press back further onto the table top away from the edge. Since the press is lifted up, you'll have an easier time placing C-clamps too.
• I found the Dillon easy to operate, but the method of adjusting the powder measure just didn't come up to the standards of the rest of the press. On Ebay I found these press-on plastic caps that turn the hex bolt end into a thumb screw. I'm sure they're available numerous places, but these things are
very helpful, and only take mere seconds to install.
• Also marking the powder measure (see photo) with a felt tip pen to indicate which way to rotate the knob was helpful.
• Also discovered that Dillon does have some deals. Check out their 10 ammo boxes for ~$10. Not worth ordering on their own, but when you order the Strong Mount or other next accessory, having those thrown in adds nothing to the shipping weight, and they are great boxes.
Enjoy the new press.
