Due to waterfowl shells being practically nonexistent last yr I dusted off the MEC and got back into loading steel again...Primers were also nowhere to be had so went to the bone yard and found a K of old Alcan 220 's stashed away since the mid 70's I guess.
After load testing via chrono and no issues I used them to load several cases of 12ga both 2-3/4 and 3" with excellent results no misfires..
Being they're over size a tad I'll use the primer pocket tool to restore fired cases back to spec when 209's are again available..
