The bad:
1. Both are fidgety to setup and caliber change over requires adjustments.
2. They are LEE products and while the quality is decent it's not RCBS or Dillon.
3. The ACP will let the user prime too fast in my opinion. I have trained myself while priming to slow down. One slightly misaligned primer getting pinched with a fast pull of the lever could very easily cause a detonation.
4. The feed system will jam up from time to time if not lined up exactly.
5. The APP has to have the LEE X series dies. Not a big deal as their inexpensive.
The good:
1. Speed, blistering speed especially for case sizing. No kidding, I can hit 1000's of cases an hour on size/deprime once dialed in.
2. Changing sizing dies is fast thanks to the breach lock system.
3. Feed system with the four drop tubes works really well. Sporadicly I'll get a case flipped backwards. The smaller the case the more this happens. It's not a big problem as it's easy to clear..
4. The ACP has excellent primer seating feel. I can feel the difference in case makes as I prime. It also has plenty of leverage for tighter primer pockets and the feed system works well. It's honestly the best automated primer tool I've ever used.
5. The four tube magazine with the sorting tray (don't remember what LEE calls it) is a must have addition.
Conclusion:
If you load ammo in batch's buy them. The speed advantage they offer is just amazing.
Thanks,
