My impression from what I'd read is that nearly anything that's got enough impact energy to penetrate clothing, soft flesh (denim & ballistic gel) and the hard bits of thorax, is going to get through perpendicular drywall very easily.
Here's the lightest round in common use, 22LR, holing 8 layers of drywall sequentially. This is 1/12th as much muzzle energy as .223:

Here's pricy specialty frangible rounds designed not to go through walls... still going through walls in a test:

It just becomes dust when it hits something hard that would normally bounce a bullet.
