Don't be so rash. The Autodisk Powder measure works quite well. It comes with a instruction sheet which will tell which disk to use based on the type and amount of powder you will choose.
Depending on the powder you will use (and it appears you want to use Unique), it may throw a slightly lighter charge than listed, but it's pretty consistent. Just be aware that some powders meter better than others depending on their density. Unique powder meters pretty well.
The kit also includes a magnetically suspended scale which I found to be very accurate. You should throw a few charges and weigh each one individually to check for accuracy and deviation, then throw 10 charges into a pan, weigh it and divide by 10, it should average to what you are looking for.
In a pistol reloading setup, the advantage of the Autodisk Powder Measure is that it removes one step from the reloading process. It drops the charge through the expanding die, as you bell the mouth of the cartridge. Very convenient.
If you plan on reloading for a rifle, first of all, the Lee Deluxe turret only works with .223, it's not tall enough to accommodated larger cartridges. Also the Lee Perfect Powder Measure is much more suited for this job than the Autodisk.
FWIW, this is the same kit I started with. I since added a few more tools, like a digital scale, calipers, specialty dies, a couple of powder throwers, but by in large it's almost unchanged. For rifle I actually use a Lee Handpress because it can accommodate the larger cartridges, and I don't load nearly as much as I do for pistol.
Edit:
One thing you might want to consider, is using the press in single stage mode. This turret press has an auto indexing feature which is designed to produce one shell with 3 or 4 consecutive pulls of the handle, but until you feel comfortable and trust your equipment
and yourself to produce consistent results which each pull, I would remove the indexing rod, and basically do all your shells one stage at a time, then manually rotate the turret for the next stage. It slows the process down, but it lets you inspect the results on each and shell at each individual stage.
Good Luck.
