I had always used CCIs too, then I bought some Federal Match primers for a couple of guns. Still have CCIs but the 215Ms are reserved for certain rifles. I see no reason any of the primers would be bad at this point take what you can get. I have a hard time paying as much as they want for them though. I'll take what I can get when I can get it, I just don't want to pay $120/1k. I did specifically intend on using 215Ms in the 28 Nosler I was building. Before all of this it was only CCI on my shelf now I have a mix of CCI and Fed from pistol to rifle sizes.
