The ALCAN Shotshell Reloader's Manual No. X is bound into the First Annual Edition of the Handloader's Digest, LC 62-15069. That ALCAN manual contains a fair amount of information about the various metal shotshell cases that ALCAN once marketed. Please note that none of the loading data in that 1961 or 1962 manual can be considered current (2008) laboratory tested data!

Thank you for posting those pictures!
