Mfr. No.: E-10-2430

757253996672 Oversize Expander Ball Soft seating of bullets is a technique used by many top competitors to overcome variables such as inconsistent seating depth and seating depth changes due to throat erosion. Soft seating of bolt action rifle ammunition is accomplished by leaving the bullet seated out far enough so it is pushed back into the case as the rifle bolt is closed. Thus, each bullet is started true to the rifling. Note: Maximum pressures should be approached with caution when loading with this method. Oversized Expander Balls are designed to replace the standard Expander on Forster Sizing dies. These larger Expander Balls produce reloads with lighter bullet tension, allowing you to precisely control bullet release.
