Use the Omega for my reloading too,along with 2 x Chargemasters and a Sartorius.
The Omega is really the only trickler suited for the task of dropping single kernels with repeatability, and it does so excellently.
When you get it the first time take your time and fiddle with the adjustments to get it right.
The only complaint i have about it is really that it is very slow to feed out the powder everytime it is empty.
Arkhangel's tip is also good to some degree.
A better option still,like i have done. Is to buy weight certified weighing dishes that will fit the chargemasters, check the weight of all of them on the balance just for reassurance, and simply replace the ones that are filled with powder with new ones instantly as you take one off , gives you no downtime on the Chargemasters.
As for the preset underthrow weight, check how the tolerances of your Chargemasters and set it as low as possible without getting overthrows, usually 0,3-05 grains.
2 Chargemasters gives me no downtime, but i do Neck size on the single stage, fill in powder through the drop tube, seat the bullet with the hydro seater arbor and sort the loaded rounds by seating pressure, in one go for every single case.
Just to achieve as consistent neck tension as possible, the overall speed is not really affected much anyway as long as your bench layout is right.
working them over in batches is what most does i guess,but fx sizing all your brass one day and go back to dispense and seat next day will affect the consistency of your neck tension or at least seating pressure compared to doing it the way i do it.
