[QUOTE="Centre Punch, post: 133565, member: 3048"] Hi Reloader, I Think that my interpretation of "cant" is what yourself and others would call bullet run out. Let me explain what i mean by bullet cant. If the seated bullet is tilted to one side or its centre line is at a slight angle to that of the case that is what i call "cant" Bullet run out to me is when the seated bullets centre line is not on the same axis as the centre line of the case, so when you roll your finished round under a DTI you have a high spot on the bullet. That corresponding high spot appears on the case neck at the same point ( providing you have concentric necks ). I therefore regard bullet run out as a factor of case body/neck missalignment. Like i said this can only be corrected by ensuring that both the C/L of the bore of the neck and the C/L of the case diameter are on the same axis. Ian. [/QUOTE]
