Dillon seating die for SWC

[Jmoser]

Finally ordered these for .45 and 9mm, highly recommended for semi wadcutters engaging on the shoulder for true alignment when seating.

How is that different from the insert in a Dillon seating die that has a contour for round nose bullets on one end and a contour for flat nose bullets on the other?

Dillon OEM stem flat end hits the nose of the SWC and can tip it crooked. This one is counterbored to clear the nose and engage the shoulder- much better in line seating force.
We all loaded 124 9mm LSWC for PPC and had issues with the stock Dillon die. I have an old style Dillon (pre quick change stem) and it works OK but the mod is a big improvement.

Gotcha. Thanks
