I have about 20 some cases marked "IK" "30.06", with central flash hole, red primer sealer and faint annealing mark. Looking on the International Ammunition site https://cartridgecollectors.org/?page=headstampcodes shows factory
Igman Zavod, Konjic, Yugoslavia as manufacture. Anyone familiar with them? They check as nearly sized but a few thousands short of minimum case length. I would like to reload these for informal shooting with my M1 Garand.
