I wana pick somthing else up besides target loads to keep in my night stand and practice abit with the rest vs jugs...If there any reason to use 00 for walking around shooting clays, watter jugs, ext... I hear over all even #4 is recomended for home defence because 00 can penetrate walls easy and kill others in your house. Should 00 buck be reserved for hunting, ext or it is an ok target load. These are the only 2 i can find in bulk for a decent price the 00 being more expensive.
#4 will do just fine. It is designed more as a heavy bird load but will work in a scenario where there is a break in and you have enough time to call 911, then open up your safes, retrieve a shotgun, load it and used it for self defence. If the criminals haven't gotten to you yet, chances are they are there as thieves first and violent offenders second. These types of criminals will be scared off when the lights are turned on, you announcing that you have called the police or worse case the sound of a shot gun blast. They will scatter and if you happen to hit one, #4 will allow someone to stumble out of the house before dropping or running away. They will be apprehended when they find their way to the hospital.
Everyone who thinks that they will use a firearm for self defence in their house at one point in they lives, should conduct an experiment that involves a controlled live fire simulation or take a course where there is one. People will be surprised about the different variables and effectiveness of each firearm. We trained in an old house and compared the difference between a handgun, AR rifle variant and a shotgun without ear protection and factors such as sight, sound, movement and acquisition of target are eye openers and put an 18" pump above all in my books.
As for loads, as I mentioned #4 will do unless you encounter an extremely violent home invasion but in a scenario such as that, things happen much more quickly and you may not get a chance to get to a weapon or the criminal may acquirer your weapon before you do. But in the off chance that you do, the best shot to have is the 00 buck. Standard in the military and used by all law enforcement, 00 buck is designed to drop medium to large game or humans where they stand. For all those who don't believe that violent home invasions happen in Canada please look up the Jennifer Pan case in Toronto which occurred a few years back. The reality is that most if not all home invasions are people who are targeted so the rule of thumb is don't make yourself a target by doing stupid things like flashing around money or bragging about what you have. In the Pan case, it was a combination of poor parenting and a bad kid but never the less, it was a targeted home invasion. Now, if someone is ready for a home invasion and have no problem killing someone in their home then that individual is either in the wrong neighbourhood, wrong occupation, have bad acquaintances or just enjoy drawing attention to yourself and pissing shady people off. In a previous life, that was my job and in during one situation I had a double break and at the last moment I switched from #2 to 000. It wasn't a good feeling but it got the job done fast. We all live with sins and in this life this is part of my burden. I am still messed up to this day and my wife who wasn't even there lives in fear and paranoia even though we live in a very nice area where the crime rate is as close to zero. This really isn't the best way to live.
Guess what I am trying to say is to arm yourself but arm yourself accordingly. Normal people have break ins but if you are preparing for a home invasion, you are either doing something wrong. And if you don't have the fear of killing someone or if you don't have any remorse after you killed someone then even I know that is not normal behaviour. I live on a farm, so my shotgun is behind my door and I have #2 on hand when I know that all I need are #4s but that's only because I come from a messed up past.
