Does bullet need adequate support in the neck to shoot well?

From the FWIW Dept . I ask John Whidden that same question at the Southwest Nationals , about five or six years ago . He handed me one of his Comp rounds , and said , "Spin it" . The bullet rotated smoothly in the neck . He called it "soft-seating" since he does seat long , and let's the Leade control his seating depth . I guess you could say "support" is relevant .

How long was he seating it, like . . . into the lands?

More or less . As soft as the bullet was in the neck , I would guess it would "Base-out" when it came in contact with the Leade .
