[QUOTE="bigedp51, post: 1308688, member: 28965"] At the Whidden custom die website they tell you they get the most concentric cases with non-bushing full length dies. Body die are associated with bumping the shoulder back when necessary when neck sizing only. I prefer full length resizing with Forster benchrest dies and belong to the rat turd in the violin case club. :D [IMG]http://i.imgur.com/Y3IiYL5.jpg[/IMG] Below Germam Salazar is replying to a "partial neck sizing", and with a full length resized case the body of the case has no steering effect on the bullet and gives the bullet "wiggle room" to be self aligning with the bore.
