If the stuff like h335,4895,power pro varmint, 4227, and lil gun are showing up and hanging around somewhat, won't be too long before the shotgun powders like unique, red dot, etc will show up and hang around.
Something to mull over is unique, red dot, etc are used in stuff like 38 and 44, well, those cartridges are still real popular with reloaders because factory ammo is stupid expensive even when nothings really wrong. So, of course they'll take longer to hang around. Seems like unique is the handgun varget from what I see.
I'm more worried about powder than primers, but I'm nowhere near panicking about it, if that makes sense.
