What are you fellows recommending?
I did a bit of reading a couple years ago about what shotshells are best for home defence. Both practical tests and theoretical calculations showed that #4 buckshot at a moderate velocity is the best. It shouldn't come as a surprise since a lot of shotshells sold as "home defence" ammo is #4 buck like that Remington HD.
The requirement in the tests I was reading about was lethal penetration through moderate amounts of clothing at "across the room" distances. Being able to punch through car doors, 2' of ballistic gel, or other things like that where considered overkill and actually negative for home defence situations.
I would want to do a lot more tests to verify but wax slugs have a lot of potential for home defence. They practically explode when they hit anything more solid than air because the wax is so weak relative to the energy the projectile has. Even being fired through a mock wall in some tests they broke up so there was essentially just birdshot coming out the other side. No one to my knowledge has done good highspeed video of wax slugs hitting ballistic gel or anything of the like. I really want BrassFetcher on youtube to do a video on it. He did do a video on cut shells and they caused massive trauma to a depth of 6-8" I believe but very little penetration past that.
If it's for HD, what about rubber shot?
The chance of being sued is always there.
If a burglar breaking into your home slips, falls, hurts himself, and successfully sues you for having an "unsafe home" imagine the case against you if you intentionally hit him with a rubber slug and breaks his ribs and collapse a lung.
Everyone and their mothers says it and I've had a police officer tell me the same thing. Do everything you can to avoid a situation where taking a life is required but if you find yourself in said situation, don't shoot to wound.
