The point you’re attempting to make in the first paragraph is too vague to respond to.
As for magazine capacities and legal (for civilians) ammo, referring to inside the home is irrelevant. Applicable federal/state laws will apply whether in or outside of your home. And AFAIK, MA is the only state that requires firearms in the home to be locked up. I have firearms in my home that are always loaded, except when our grandson (almost 3 yo) comes to visit, in which case I unload and lock them away.
My opinion only, but banning full auto weapons and restricting allowed magazine capacity are two that, although I do not support the idea, would have no effect on my ability to protect myself/my family. Reasons are simple: first, getting one is not easy (even for bad guys) and rarely does a bad guy attack with a full auto weapon. And magazine capacity deficit can be overcome by carrying additional mags (I do). Yeah, yeah, I know the argument about lost time changing out mags, but part of gun ownership responsibility is proficiency in use. Practice shooting, practice mag swap outs. Again I’m not endorsing anything, just sayin’.
