There is so much mythology out there about these two firearms, that I thought a thread discussing this topic might be worthwhile.
First, let's take a look at how these two calibers behave in ballistics gel. Here is Brassfetcher's testing of 12 gauge Remington Express 2 3/4" 00 buckshot through heavy clothing. The relevant statistics for 12ga are:
Deepest penetration depth : 16.0+ inch
Maximum crack diameter : 6.0+ inch
Maximum crack diameter location : 4.5 inch
Cavitation depth : 0-15.8 inch
Now let's compare some common .223 loadings through heavy clothing:
The first thing you'll notice is that out of the different .223 loads, only one outpenetrates 00 buckshot. The second thing you'll notice is the ruler at the top - it shows that the maximum cavities and the depth of those cavities isn't dramatically different from the 12ga 00 buckshot.
However, if you don't trust eyeballing it, here are some stats from Hornady LE for their .223 75gr TAP BTHP:
Deepest penetration depth : 12.0 inch
Maximum crack diameter : 5.5 inch
Maximum crack diameter location : 5.25 inch
Cavitation depth : 0.5-9.5 inch
Now let's look at a cross section of an average human torso:
An average male torso is approximately 9" deep and 19" wide.
Assuming we are barricaded up and waiting for police to arrive when the bad guy comes through the door, you can do a mental overlay of either wound profile on top of the torso above. In terms of room for error for shot placement, we are talking approximately a 1/2" difference between the Remington 00 buck and the Hornady 75gr TAP.
As you can see, both firearms are plenty adequate to do the job and with both firearms penetration can be limited by proper ammo selection. In terms of drywall penetration; both the 00 buck and 75gr Hornady will still have enough force to be lethal after penetrating a typical interior wall.
