May have been a better product back in the day... - Hornady Lock-N-Load Power Case Prep Center 050012

Just for some background, I'm an old buzzard. Been reloading since the mid '70s. Having recently processed 600 5.56 military cases by hand, I had to admit my time hand-twisting case prep tools was over. The Hornady Lock-N-Load Power Prep Center is the most expensive tool of its type I've found, but the price would be a non-issue if the tool performed as shown by Gavin of Ultimate Reloader. It may have once, but my specific example is truly awful. For starters, the case trimming cutter is rather dull, relative to my 30-year old RCBS hand-operated unit. The RCBS unit will cut as little as .001", even showing an ultra thin sliver shaved off. The Hornady shows a few slivers but doesn't really shave off the brass; more like pushing it aside. If only removing one or two thou, the result looks pretty normal - ready for deburring. But if removing more than say, .005", the cutter spits out a few small chunks, then heaps the rest of the brass into a ledge on the outside of the case mouth. Following up with the chamfer and outside deburring tool is a bit frustrating, as the 4-bladed, rather dull, de-burr tool breaks off the swarf, replacing it with its very own ridge - a ridge I then removed by hand with my old L.E.Wilson de-burr tool. Time saving?" Not so much. One good feature - the inside chamfer tool is very sharp and efficient.

Back to the case trimmer. Setting the depth of cut isn't too difficult, though learning the drill takes some practice. Even so, finished cases can be expected to be within .002" of each other, at best. As for the claim that the small serrations on the depth handle equal .001" change, I'll have to take their word for it. My experience is sometimes yes, often not. But here's the deal-breaker - the spindle holding the shell holder is spring-loaded and operated using a T-shaped lever, which bears down on a ball bearing held by a hand-wheel/nut. Sometimes, something inside the spindle bore snags in the full down position, then breaks loose as the lever is raised and flies upward to its stop with a loud snap sound. A few of these episodes mangled the spindle stop pin.

So - trimmed cases need to be checked for length, as each one seems to differ from the previous. Time consuming.
De-burred case mouths must be checked for a machine-induced burr and corrected. Time consuming.
Installing/removing a case in the shell holder takes more time than with a hand-operated unit...unless you don't mind using your fingers in close proximity to a spinning cutter blade.
Frankly, carpal tunnel aside, I find hand-processing using sharp, high quality tools to be faster and more accurate than using this case prep center. Instructions in carton state to not return unit to store - must call Hornady for assistance (but not a return). Otherwise, this Case Prep Center would be on its way back to the seller. Caveat Emptor
