Did you look at the Henderson? I've used both and feel the Henderson is much better ... assuming you can afford an uplift.
I have the Henderson, a friend has the Giraud and I've used it.
My takes on both:
Indexing:
- Giraud indexes off the shoulder, Henderson indexes off the case head
- Giraud will yield different overall lengths based on sizing consistency
- Henderson will yield different neck lengths based on sizing consistency
- Which one is better? I don't think it matters unless you're trimming precisely to chamber length. The Henderson will be better in this regard, but will give up some variation in neck length. That variation is not material, however. Assuming you're +/- .001" on sizing, that's on the order of 1% difference in effective neck tension. That will get lost in all the other variances.
Accuracy:
- Essentially the same.
Throughput:
- Edge goes to the Giraud, but not by much. They are very close in seconds per case.
Ease of Setup for Different Cases:
- Henderson has the advantage here. Much easier to access what you need, and no special tools required.
- The length is set by using a very simple hardware-store-available bolt and locking nut.
- Aside from the cutters, which are universal by caliber (e.g. same for a 308 as for a 300 PRC), it's all off-the-shelf stuff.
Size:
- Edge goes to the Henderson.
Noise:
- Advantage Henderson.
Cost:
- Advantage Giraud
EDIT: I forgot looks.
Looks:
- Big advantage to Henderson
