I’m considering upgrading my brass trimming setup and am particularly interested in the Hornady 3-in-1 Power Case Trimmer. Its capability to trim, chamfer, and deburr simultaneously sounds appealing.

However, since I reload for 10+ rifles and regularly add more calibers, having a trimmer that doesn’t require constant purchases of separate caliber-specific attachments is very important to me.

I’d greatly appreciate hearing from reloaders who have experience with the Hornady unit:
  • How precise and consistent is it across multiple calibers without additional attachments?
  • Is caliber changeover quick and convenient?
  • Have you encountered any significant limitations or issues
Also, if you’ve used other top-end automated trimmers like the Giraud Power Trimmer or the Mark 7 Power Trim Xpress, how does the Hornady compare in terms of ease of use, flexibility (particularly regarding caliber changes), and overall satisfaction?





Thanks in advance—I appreciate your insights!
 
There's no way any list of trimmers wouldn't include the Henderson at the top of the feature list. I've tried several before I got my Henderson, and once I had it configured ... I've never looked back. Nothing I've seen is as easy, fast, or has more features. It's expensive ... true ... but if you're into this hobby to save money, you're likely to be disappointed. Bottom line ... the Henderson Precision Powered Trimmer is the state of the art in this category, IMHO.

What about caliber change. Is it easy? Does it include buying new caliber changing sets

I have cutting elements for all three of the calibers I reload (6.5, 300, 338) and pop them on and off regularly ... it's easy. I also have a "sizing bolt" for each caliber so that I never have to do fine adjustments ... the length is set and stays set.
