This guide addresses a common reloading problem where bottleneck cartridges fail to size correctly for chambering, even with a properly adjusted sizing die.

He strongly recommends matching the shell holder brand to the sizing die brand for consistent results. For advanced users needing precise control, he suggests incremental shell holder sets like those from Redding to fine-tune sizing for different brass lots.
