Rimfire .22 LR Penetration Tests Yield Surprising Results
The .22 Long Rifle (.22 LR) round is widely regarded as a relatively weak cartridge with very little penetrating power. Compared to most centerfire ammo that’s certainly true. But the venerable .22 LR actually packs more punch than you might expect. A recent test by rimfire specialist 22Plinkster demonstrated that the little .22 LR has enough power to drive a bullet through multiple walls.
In this video, 22Plinkster tests two types of .22 Long Rifle ammo, seeing how far a .22 LR bullet will pass through sheets of 1/2″-thick drywall. He shoots CCI Velocitor and CCI Stinger ammo types from both a pistol and a rifle. The results may surprise you. Shot from a pistol, the CCI Stinger ammo penetrated Nine (9) drywall sheets. Out of the rifle, the CCI Velocitor Ammo passed through Eleven (11) sheets, while the CCI Stinger stuck in the eleventh board, after passing through Ten (10) sheets.
The rimfire ammo’s penetrating power surprised .22 Plinkster: “I was really surprised that [the ammo] went through as many [dry wall boards] as it did. I was thinking four, maybe five tops …” He points out that the rifle penetration of 11 sheets was “equivalent to five walls, maybe six walls. If you were shooting in your house, and you had 1/2″ drywall, it would go through five walls. Now, that’s pretty scary that a .22 Long Rifle could do that.”

I would be interested to see if a 22 would penetrate 5-6 walls in an actual house environment. The distance between walls in a house are generally anywhere from 4 to 20 feet apart instead of 3 1/2″ like the picture depicts. As with all firearms they do need to be treated with respect.
.22 lr must never be taken for granted. When something has been in continuous use since the mid 1800’s it means it’s kind of perfect.
For those who keep saying that .22LR is not capable:

It wasn’t even LR, but Long!
I think drywall with simple insulation vs drywall alone could make quite a difference not only on the type of insulation some being thicker Atleast how much resistance you are getting also considering various types grains jackets barrel lengths and wear and tear I haven’t seen a. 22 penetrative a tree at all barely enough to flatten and stick to a tree at close range vs a tree likely to hurt yourself before the tree they bounce right off.
Also looking at vapour barrier in addition to insulation which even of rockwool and clear plastic type can vary alot in density and is obvious when you cut it and how much extra material can be stuffed into a space of the less density insulation.
