Just to throw a slightly different perspective out there I actually use a .410 for home defense and well as take a JUDGE with me when i travel. My biggest concern is always wall penetration I would hate to shoot threw a wall and hurt or kill someone on the other side. The new defense loads from winchester are also great disks and shot in one package makes for a nice way to tell some one they are not welcome in my house
Thanks; just learned what a Judge is. Good point about wall penetration especially here in Cali where houses are made of tortillas -or is that really stucco - and chicken wire.
Read somewhere about buckshot that's lightly coated with rubber to kill zombies but with less fear of wall penetration.
Pardon me but the penetration issue is a pet peeve of mine...ammo manufacturers and talking heads have convinced people there's such a thing as a magic bullet when there really is not.
If you're worried about killing someone on the other side of a wall you shouldn't be shooting in that direction, period. Most homes and apartments have sheetrock walls which you should consider as nothing more than a few sheets of paper for all the stopping effect they have against bullets or shot. Cheapie southwest art deco stucco is no better.
Let's be very clear on this... any round that is physically capable of stopping a bad guy will punch right through a sheetrock wall if that's what it hits first. Combine this reality with the knowledge that statistically more rounds fired at bad guys are misses than hits, and it quickly becomes obvious that if you shoot at a bad guy in front of a sheetrock wall you will likely have a couple of misses that hit the wall directly, and go through it, without first going through the bad guy and slowing down. Rounds that can penetrate a human deep enough to reach the critical CNS to stop someone will typically go through 4 or more layers of sheetrock if that's what they hit first. Thus, any round fired that could stop the bad guy, if (when) he's missed, can punch through a wall and injure or kill on the other side.
There are ways around this if you plan ahead. In a typical family home you will know where everyone's beds are at, and should be able to pre-determine safe vs dangerous lines of fire in a home at night when everyone is sleeping. You can also set up a family plan where a shout of "COVER" gets everyone to predetermined positions in all rooms of a house where you will know where to not shoot at. In apartments you can also figure out where neighbors will be through the day and be able to make a guess whether it's safe or not to fire in a given direction. The guess may be off, but the call will need to be made on the fly to shoot or not shoot. Plan ahead accordingly. Take advantage of being on home turf when invaded (even while traveling in a hotel room, you're there first and can scope it out). Plan lines of safe fire, and know what are dangerous lines of fire, and position yourself during an event, if you can, to maximize your ability to safely fire, and don't shoot if you likely have an innocent person behind the attacker, or likely behind a wall behind the attacker. If you let a bullet loose you own the consequences of what it does.
Attempting to get ammo that won't penetrate a sheetrock wall, but will incapacitate an attacker, is like asking for a shoe that fits a size 14 foot on the inside but looks like a size 7 on the outside.
Sorry for the rant, but I hate to see guys snookered into buying snake oil only to find out later they were misled.
