I`ve seen the OEM small rifle primers on shelves around here a couple times in the last month or two. I called CCI and was told they are the same as their CCI mag primer for loading purposes They are normally sold to wholesalers that feed the small ammo/reloading companies though, and not the general public. Their take on my seeing them in a gunshop was the shops wholesaler must have had some extra and decided to make a quick buck. Whom that dealer was they couldn`t or wouldn`t say, and didn`t really seem too excited about it. They did tell me they were fine to use if I wanted. Normal load work up as one should always do with every new component change was recommended.
