Re: Gracey trimmer
I have a Gracey and like it a lot. But it is a pain in the butt to adjust the cutting blade for different calibers. There are two blades and there is an art to moving them just right. Kind of like taking-down a Ruger 22 auto. Once you get good at it it's no big deal but you do it so infrequently that it can really drive you nuts sometimes.
For a long time I only used it for .223, doing 1000's, and used a crank style Hornady for other calibers that only got loaded a couple 100 at a time. If you're only doing one caliber a Gracey is golden.
The Giraud is nicer in proportion to the cost. Better motor, drive system, bearings. It also uses a one piece blade. The blade is still a pain to adjust between calibers but about 1/2 easier (1 vs. 2 blades).
They are both nice because they trim and inside and outside chamfer in one step, just push the case in, twist a little, and you're done. Most other trimmers require multiple steps.
How many cases will you do a year? 10,000s = Giraud, 1000s = Gracey, 100s = Hornady or RCBS.
If you are only doing a hundred or so at a time between caliber changes I'd stay away from Gracey or Giraud.
