Ive been reloading a fair bit lately (dont we all

Just lately, I have seen a few odd items in the 2208 powder ive been using - like (what seem to be) sticks of powder up to 12-15mm long, bits of what look like sand with a coating of graphite, and a hair from a brush of some sort, complete with powder coating and graphite.
Weird, anyone else found "greeblies" in their powder?
