I haven't reloaded shotgun shells since the mid 60's
I dug out and dusted off the old Herter's 12 ga shotgun reloader, dug out old boxes of primers and wads...wads were old Alcan Flit-Max. The paper cases were also ALCAN.
fortunately I still had primers from the 60's era that fit the Alcan paper cases.
then reloaded both #6 and #8 1-1/8 oz.
