This was tested with a Henry Lever Action Rifle and a S&W M&P 22. The purpose of the test was that there are some people do use a 22 long rifle for home defense. If they missed their target and hit the drywall in their home. The video was demonstrated by 22Plinkster and discovered most of the .22 rounds went through 9 drywall and some into the tenth drywall, its very impressive for a 22 round. See the test here.
