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.
Yes, I have some of better quality Aquila .22 ammo, but would not have bought it if supply was not so short.
I only have 3 .22 rifles, a lever, a pump and a single shot bolt action rifle. No pistols.
I reload all of my other rifle calibers and .38/357 pistol. Have a 9mm pistol, it is a collectors gun, I don’t reload for it. Don’t like to shoot 9mm
I have a .22 CO2 pellet gun and a .177 caliber pump up BB gun. They shoot cheap. Work fine for birds and squirrels. Have killed several rattle snakes with the pump up air rifle. They are bad to get into my implement shed.
