I run the Hornady L-N-L powder measure, the Dillon powder measure, and the Lee Pro Auto-Disk powder measure. The Hornady is the most consistent, but I have not been able to get it set up for my son to reload .380 Auto using the .355 PTX (when he wanted to start reloading, my wife "suggested" that I give him my L-N-L since I had enough Dillon 1050s). I personally think we need a longer PTX, but when I next see him we might just call Hornady and have them walk us through it.
The Dillon, with cartridge specific "powder funnels" (their term for the powder-through die insert), is very easy to set up and will generally stay within +/- 0.1gn with most powders. I recommend it for those who are more concerned with fast set-up than ultimate powder measure repeatability. I really like it. The only complaints I have are the adjusting bolt changes the charge weight quite a bit for a very small change and it, like its predecessor, the Lee Auto-Disk, can leak with very fine powder. Finally, the Lee PAD is just so simple to use that I will always have at least one around.
If you load cast or swage lead bullets, get the larger "lead" PTXs.
