What Erick said.
Each shotgun's a law unto itself as to what works best. Buy a couple boxes, run some pattern tests, buy a messa whatever is tightest. The most expensive load out there will not break the bank.
Since this is a HD load, use a long tape and measure the longest possible distance for a shot opp inside your house, add a yard for GPs and pattern at that distance. My guess is that unless you live in an abandoned high school gym or subway station, patterns at your longest distance will be one bore sized hole. This is why "Serious" shotguns get AIMED.
Also why many of us believe a less penetrative load like birdshot is a good choice for HD, at least for "First Up"...
In fact, a load of breath mints oughta work at inside range. Shotguns dump impressive amounts of energy into a target.
Skip the magnums,here's where the term "Overkill" really means something. All they'll do is build a flinch and go through your discretionary income faster.
