Over the weekend I pulled the bullets from some 22 Hornet ammo that I bought at a club auction, and was extremely surprised to find that about thirty cases which are marked as "ICI 22 Hornet", have twin flash holes and a standard sized mall rifle primer. The cases were obviously bought as factory primed cases as they had never been fired, inside is perfectly clean. Has anybody else ever seen 22 Hornet cases like this before ?
