Redding 10mm Auto Titanium Carbide Die Sets

[REDLINE]

Redding shows two different standard Titanium Carbide Die Sets for the 10mm Auto.

One is part #88253 labeled as - 40S&W/10mm Auto

The other is part #88520 labeled as - 10mm Auto

Anybody know the difference between the two?  Is there a difference at all?  I attempted contacting Redding to ask but they are in the middle of a 2 week plant shut down and won't be available till Monday August 13th.

I don't "know".

If I were to guess I would guess the seating/crimping die is built differently enough that it can't be adjusted to work on 40S&W.

The original 10mm dies being made before the 40S&W came along would be my guess...My RCBS 10mm die set was one which was produced prior to the 40S&W evolution thus the crimp die would contact the shell holder beforebeing deep enough to make full taper crimps.

I question that the dedicated 10mm set came out before the 40/10 combo set, with the part number for the dedicated set being a higher number.  Though that proves nothing.  Can't wait till I find out for sure just what the deal is, and, if there is a benefit either way in regard to the 10mm itself.

Most, if not all major die mfg's had retail 10mm sets on the shelf years before .40 S&W was hatched.  There was no reason to accommodate a shorter cartridge, so they didn't (intentionally).  It was a tough choice back then, with new everything.  New cartridge, newer die technology, powder evolution, mfg's trading in/out like baseball cards, new guns (old imports and new mfg's), new mfg technologies (CNC), etc.
