Aguila .22 shells burn dirty. They shoot OK.
And they have a distinct odor.
Any .22 shells are very valuable today. As is all ammo.
I saw signs of a shipment of some PRVI Partizan (PPU) CZ made ammo today at one of the on line distributors. It won’t last long. I did not order any because I’m only looking for a couple of calibers of brass right now.
Beat me to it. They do burn dirty and the burnt powder has that distinct stink. It normally reserve it for the .22 revolver at the range, but due to the ammo shortage I had to use it during an Appleseed weekend.

The Ruger 10/22 took it though without a single problem and the stink is noticeably less outdoors.
