[QUOTE="Mikecr, post: 928830, member: 1521"] No, this is JUMP(roughly). Freebore is set by the chamber reamer, but there are several common ways to consider it: -Chamber neck end to land begin -Chamber end to land begin(lead) -Same references but to ogive contact(as set by ogive radius/type & leade angle) The value that matters to me is seated distance to land contact -per bullet. Predicting this up front for filling out a reamer print, etc, is not very easy. Best done with a program, and reamer makers can do it for you. [/QUOTE]
