length

Length is a measure of distance. In the International System of Quantities, length is any quantity with dimension distance. In most systems of measurement, the unit of length is a base unit, from which other units are derived.
Length is commonly understood to mean the most extended dimension of an object.Length may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, measuring across the object at right angles to the length.
Length is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed).

    Minimum Case Length ? With Pistol Brass.

    What if any is the danger in using straight walled, non-rimmed pistol brass, that is 1mm (.040 in) shorter than max case length? Edit: And what source do you use to find minimum trim length?
