True dat, but extra smoky from pressure reduction.

Unburnt propellant is smoking because of pressure reduction prior to fully burning.

Progressively burning propellants become highly inefficient when pressures drop prior to complete burn.

Unburned powder and lube, buld up and eventually start to burn off as exposed to more and more heat. Shorter the barrel the more unburned powder , the more lube , the more to retain it. Also the pistol is just closer to your face than the end of a rifle so you notice it more.

I think that might explain smoke from the first round if you don't run a dry patch or 2 thru the bore before shooting, but I doubt the oil would still be there for the 2nd. Frankly, I've never noticed excessive smoke from a .22 and I've fired tens of thousands of the stuff over the (many) years so I'm probably just not very sensitive to it.

I'm in the old shooter camp. If I think I'm not going to shoot again soon, I leave a liberal amount of oil in the bore. And if I forget to run a dry patch to clear the oil I get smoke for maybe five rounds, maybe more, I've never really paid close attention.

Observation from yesterday morning and 50 at 100, 50 at 200 yards.
Extracting the brass after each shot fired, a wisp of white "smoke" curls out of the breach.
The "smoke" dissapates within an inch or two of the receiver.
So it's not "smoke". Blow out a candle and the smoke will rise up quite a ways before dispersing.
Each time the brass was pulled, that small cloud followed and rose up.
By the time it was a couple inches clear it evaporated.
Yeah, evaporated...I watched closely. It's steam, produced by the combustion of powder/primer.
If y'all hadn't discussed it, I'd have never given it a second thought.

Smoking 22ís

Recently I was using up some partial boxes of older 22 ammo. The wax lube on some of it was sort of dry,hard and some would even flake off. I had some Lee lube and Alox-beeswax lube , so I smeared some of that on the 22 bullets and fired them out of my K-22 at the plate rack. There was not much wind so all the smoke stayed in my general area on the line. I like the smell and it did seem to keep the skeeters away.
