I pulled a couple of different rounds of 22LR and examined the powder. Hard if not impossible to tell what kind it is. I have to say CCI Stinger rounds are the most cleanest 22LR round I have ever shot. I guess you get what you pay for. So would you say the big ammo companies are using a fast powder like Clay’s or Titegroup or maybe something a little slower like Power Pistol or AA #5? Just curious to see what people think.

They use "bulk" powders that are specially formulated for the .22 Long Rifle. These powders are different than the "canister" powders available to handloaders.

Trying to figure out what powder is in a factory cartridge by looking at it is at best misleading, and at worst, dangerous.

The only way you would know for sure what the powder is, would be to ask the company that loaded it, and they probably won't tell you.

A good friend is a commercial reloader and has been written up in Guns & Ammo Magazine. He is working on a propriatary .22 round and in his discussions with Hodgdon and Accurate Arms, they would only supply him with .22 LR powder if he agreed to sign documents that said he wouldn't disclose the loading data or supply the powder to other people.

Hope this helps.

VV3N37 is listed in their manual as "This is a special powder developed for high velocity rimfire cartridges"...

22 LR ammo has a working pressure of around 25k psi as I recall, and slower type propellants, especially in "stinger" type ammo would seem to be what is required to keep pressures in check.
