[QUOTE="Deleted member 46119, post: 1343597"] [USER=101859]@Alex Wheeler[/USER] has that correct. However. .. Depending on the cartridge, type of load and type of shooting, .002 to .004 is a good starting point. Meaning the ID of the case mouth is less than the bullet by that amount. The actual "tension" is a more complicated thing involving stretch to yield, clamping forces and things I don't know how to describe. As I understand it. The idea behind .003 "tension" is to avoid yield. Yield "works" the brass changing hardness. Changing hardness changes clamping forces and release consistency. A .003 "tension" might not be perfect and if used for any hunting where the ammo could receive rough handling more tension might be better. Remember to anneal or your "tension" will change over time.
