The brass sleeve blanks don't all stick out equally in the hand-loading check for our FR5 proposal. The sheet records nothing about individual blank length or the end presented to the stop. I can't teach a distinction we haven't measured.
They did. One blank has a damaged end and is excluded pending quality's decision. On the conforming group, different lengths explain the different stick-out under the same verified seating arrangement.
Sheet revised, Luis, and damaged blank retained, Jo. Trainer now has separate examples of length variation and an end needing investigation. The automatic loading method still needs its own assessment.
