Re: H & H Concentricity gage or Bersin or ???
I obviously don't like ammo-benders.. But of the two this is what I see:
-The Bersin purely shows seating errors, and or neck offset, while eliminating all else from measure. It's adjustment focuses on seating error resolution.
-The H&H brings more total runout into the picture, but still masks most from measure. It's adjustment is the same as the Bersin, but would correct a touch of 'banana' from the case as well.
So of the two, I would go H&H.
