I have a CPS and love it for how quickly I can prime brass and how consistent it seats. It's the fastest and accurate tool I've found. I have a 21st Century hand seater that has .0005" increment settings. I can seat primers just as consistent but at a fraction of the speed of the CPS. I use the hand seater when load testing and the CPS the rest of the time.
For kicks and giggles I decided to test the seating depths. I went to the range with my Dasher and rounds from .003" to .010" seated primers. I'm using Alpha brass, CCI450's, Barnes 112's, 31.5 grains of Varget in a 26" barrel. I had five shots of each with a couple having seven. 006 and .009 were only three shots each and only two each registered on the labradar. The rest registered every shot. Seating depths were measure with a precision dial gauge with an adapter I made for the case rim. Each depth measurement was confirmed multiple times for consistency.
This needs more testing if I wanted to go further with it. Those .7's are larger than most every time I shoot this rifle. Last column is SD/ES.
