Hornady Size Die too small (8x57JS)

Okay, this is weird. I tried my Hornady "New Dimension" dies for the first time tonight (8mm Mauser). I attempted to resize a fired case, but met stiff resistance as the case neared the top of its travel. Not wanting a stuck case (had one of those recently in .308 with a Redding resizer), I backed the case out and noticed that a portion of the neck had been resized. It measured .337 outside diameter and .311 inside diamter. Needless to say, that is much too small for the .323 bullets the 8x57 takes. This is my first set of Hornady dies, and they seem really well made - or at least they did until they put the "squeeze" on my Mauser case. Anyone here ever have an issue like this with Hornady dies? If so, are they cool with correcting issues like this, or will I have a struggle on my hands? Clearly this is a bad die. At first I thought maybe it was sized to the 8x57's original specs, before the .323 bullet diameter was adopted. However, the original was .318 I believe, and even that wouldn't fit in a case squeezed by this die.

Never had a problem with Hornady anything, but the folks at Hornady are really nice, I'm sure they will take care of any problem you bring to their attention.
Never try to educate someone who resists knowledge at all costs.
But what do I know?

.311" after passing the expander ball on the way out?

Then it is way too small for 8x57. You need to talk to Hornady. Your die is either cut too small, or maybe mismarked (not actaully and 8mm Mauser at all). Either way, the Hornady folks will get you straightened out.
All else being equal (and it almost never is) bigger bullets tend to work better.

Thanks. I'll give them a call this week and see if I can't get this thing squared away.
