THAT, and your whole post, is very interesting information, thanks. Hadn't heard that about Blue Dot before, but then, I'm not a real reloader. I've only just recently tried to assemble an inexpensive and easily portable kit I could use to hand reload in the field, if that ever became necessary. Unfortunately, purchasing powder and primers at the moment seems to be a real problem and everything is on hold.
Anyway, I wonder if Federal Premium is admitting they use such unstable powder and priming in their ammo? If so, I'll just make sure I shoot up all mine in the next ten years and not buy any more of it! I have a quite a bit, but not so much it'll be a problem sending all of it downrange over the next decade.
I doubt that Federal is using Blue Dot for any of their ammo (I don’t know that for an absolute fact though)
Most of the time, the factories use different formulations than what is available to us peons.
Don’t know why that would be, but that is the generally accepted ‘truth’ on the reloading forums
