To better give you advice and help, tell us what you are planning on loading. Pistol, rifle, or both.
About the Uniflow Powder Measure, be sure to completely clean the packing lube from its insides, drop tubes, cylinders, etc. or it will not throw powder well.
Also, use the cylinder with the small powder reservoir for everything you can. Obviously, if the powder charge exceeds it, you'll have to use the big cylinder.
Small charges thrown from the big reservoir tend to be less accurate and uniform than that thrown from the small one.

NOW(finally) makes a
powder thru expander for each pistol size. (and they are good ones) What that means is, you can move the Uniflow to station 2 (for pistol only) and there prime, expand, and charge in station 2.
Why would you want to do that? Because then you can:
Size/Deprime in Station 1
Prime, Expand, Charge in Station 2
Powder check or Lock-out die in Station 3
Seat Bullet in Station 4
Crimp in Station 5.
And if you end up buying a bullet feeder or at least bullet feeder dies (see
$28 bullet feeder thread), optionally, in stations 4 & 5:
You can feed bullets in Station 4
And Seat and Crimp in Station 5.
The important point is...a Lock-out die is pretty important for pistol loading.
Also, If you plan to load rifle, you will need a trimmer and case prep tools.
