If you live on a farm. OkHouse defense.
If you live alone, OK
But if home defense implies the possibility that one day you will had to make use of a weapon indoors. I would consider another weapon.
Cause if you use birdshot or tripre-0 you have to consider the shot pattern and what you could hit around and behind the threat.
If you use buckshot... Only consider behind the threat because it will penetrate and go thru.
So eventually another member of the family could be at risk
