[QUOTE="jimbires, post: 2152865, member: 11011"] neck expanding with a mandrel does not push the doughnut to the outside . it might push it some , but not nearly enough . I'm forming brass for a wildcat . I'm getting doughnuts during the forming process . I'm inside neck reaming , and also outside neck turning , to completely get rid of the doughnut . you are correct , bushing dies do not size the neck to the neck shoulder junction . I'm not sure what the correct answer is on the doughnut . if you keep the bullet above it , it shouldn't matter as far as seating goes . I'm thinking it could be a flex (bend) point when the neck expands to release the bullet , so I'm getting it removed . [/QUOTE]
