.22 rimfire powder
Out of curiosity I pulled the bullets from some Federal .22 long rifle cartridges that had lain on the ground till they got soaked and would not fire. The powder was strange looking. Most of it consisted of tiny round dark grey discs. No surprise there; it looked like any number of fast canister powders, except the granules were smaller than usual. Mixed in, though, were very thin green flakes, irregular in both shape and size but mostly much wider than the grey material. They did not resemble the colored flakes in Red Dot, Green Dot, or Blue Dot at all.
Anybody have any idea what that stuff is in there for? To adjust the burning speed, or what?

The thin green flakes are the priming compound that has flaked off the sides of the case where it gets smeared along the bottom edge. 0 -

Ah. Makes sense. Thanks.0 -
I just recently took apart a W/W factory hollow point 9mm round that did not fire, it had a mixture of three different size and color round flat disc type powders ,black ,dark grey, and light grey, along with a little bit of irregularly shaped pieces of a thin green material.
Never seen anything like it before.0 -
I have seen green flakes in 22 rounds with intact priming. Varget and 322 are also green in color under the light dusting of graphite.
No, it's probably not Varget, but if Varget is green, so might other powders with not a lot of graphiting.
They use various powders because it may be more economical to mix than to process one lot into the performance they need. It may be odds and ends and leftovers, blended as well as minimally processed enough to make it usable.0 -
+1 on SoreShoulders comment about loading with a somewhat 'unkown' powder they prepare.
That's why if you find a particular load your gun likes, buy as much of that same lot as you can. Even the same 'model' round from the same mfgr may not be loaded with the same powder at some time later.0
