My hope is the forum will create a "sticky" clearly defining these two terms so we are all using the same dictionary.

Here is a SUGGESTED starting point: "C.O.A.L." defines the length of the cartridge from the base of the brass to the TIP of the seated bullet. "O.A.L." defines the length of the cartridge from the base of the brass to the OGIVE of the seated bullet using a caliper with a Comparator Gauge mounted and re-set to 0.000". Resetting the caliper to 0.000" will remove the length of the Comparator barrel from the O.A.L. measurement.

What think ye?
