Thread: Trying something, Eric Cortina method of load development

Just a note on the above, #69: threaded "modified" cases are for the OAL gauge, a measurement that M. Cortina is at pains to emphasize is not required for his method. The stock photo I posted is misleading. Please disregard the equipment on the left that appears to be the end of the OAL gauge and a modified case, and - at the risk of stating the obvious - the process instead being that each loaded (loose) round is measured with the bullet comparator, the part clamped to the caliper jaw on the right, and then returned to the seating die as required to get the CBTO all the same for a given number of rounds that will be shot as a group.
