YouTube - 14 press shootout had the RCBS Rock Chucker Supreme a close second to the CNC Präzipress for quality of ammo produced.
CNC Präzipress, those Germans. Thanks for mentioning it, never heard of that one.
Years ago I compared ammo from a LEE Loader, 310 Lyman dies in a Tru-Line Jr press, and conventionally loaded on my main press. To my surprise, the LEE Loader won. The point is that if you load carefully, you can make decent ammo. Even with my RCBS RC, I'd point the shell holder in a certain direction so it allowed the case to be centered in the die.
Much the same as building a race engine, two mechanics with the exact same tools and the same parts can build two identical engines, and one will make 50 HP more than the other one. Sometimes it's not the parts, or the tools.
Choosing a press is one of those times when a decision matrix helps make the correct choice.

For me the factors to choose a new single stage press were:
Cost, but with a low factor
On press priming, very low factor as I never prime on the press
Side access, med to high factor
Mechanical advantage, toggle design, med to high factor.
Spent primer out the bottom, high factor
Toggle over (cam over) linkage, must have
Lubrication, nice to have zerks or orifices
Alignment precision, this one is hard to factor as testing before you buy is not usually possible.
Adequate opening, I have loaded some longer ones like the H&H Mags and 338 Lapua, and if the opening is a bit crowded it gets awkward.
I bought a Classic Cast LEE, it was on sale. I probably failed to follow my matrix and got sucked in on price.
But how did the LEE CC perform.
- the toggle stop linkage was not to my liking, but I modified the linkage. Unfortunately the linkage now interferes with the spent primer tube, so I had to shorten that, it still works, just has to be emptied more often.
- The slot in the ram for the priming tool still lets the odd spent primer pop out onto the floor. I JB welded a cover in place. Good fix.
- The top link pins have holes, these allow for lubrication, works well.
- Disassembly a bit of a process, to drop the ram the linkage needs to be completely taken apart, a negative IMO.
- Alignment, this was an issue, LEE sent me a replacement top half to the ram. Alignment was still an issue so I did a bit of rework.
*** Caveat: Cast iron moves, it will stabilize, but it takes time, and several heat/cooling cycles, or it needs to be cryogenic treated before final machining. Redding presses have good alignment, they must be doing something differently, or are using a different material, IMO. That is why the design of the German Präzipress looks appealing.
My first choice was a Redding Big Boss II, and when I consider my matrix, it will beat the LEE CC on every point, except for price.
Yep, I think it's time to open the wallet again.
Anyone want to buy a heavily reworked LEE CC? Not as good as a Big Boss II, but cheaper.
