I would pass the .410 over as also to small for effectiveness.
Por que?
You made me curious.
A quick look shows 000 buck as a common .410 load... which is either 4 or 5 .36" pellets at ~1000-1125 fps.
That's roughly equivalent to 4-5 rounds of .380+P, or higher per trigger pull.
Checking a few test videos, even a short barrel .410 is going to put all 5 in a pie sized target at inside-the-house distances.
Its not a 12 gauge, but it won't knock the elderly shooter down, and beats the crap out of .22 for effectiveness, simplicity, and reliability.
A lever or pump action .410 full of 000 might be ideal.
