This custom bullet seat stem contacts SWC bullets at the shoulder, yielding consistent alignment and seating of SWC bullet profiles. Fits the Dillon SDB Bullet Seat Die† and simply replaces the original seat stem. Can also be used to seat FWC (Full Wad Cutter) bullets.
An extra deep counterbore handles most any bullet. So you can reload the 185gr or 200gr lead cast or swaged bullet without having to adjust your seating die.
Precision CNC machined from 303 Stainless for years of use. It also features a screwdriver slot on top to speed installation or removal of the seat stem in the SDB toolhead.
Available Calibers:
— .45 cal. - (T160x-45)
— .38 cal. - (T160x-38)
† This seat stem works only in Dillon Squared Deal B (SDB) Seat Dies. | ![]() |
