Want one to go with my .44 mag revolver, but would not be my go-to gun for HD purposes. If it was, I would load it with .44 special hollowpoints or something. My .44 mag revolver is loaded that way now in case of needing it for home defense. Full-on .44 mag has way too much penetration for using in a home or neighborhood -- especially with increased velocities from a rifle-length barrel. But my shotgun is my main HD gun now and my AR is a distant third on the list, with my 1911 being second.
Edited to add: no offense, but there's no way I'd use a full-on hunting rifle for HD. That .30-30 would go right through a perp and possibly out of your house and into the next house. I think that in a lever-action carbine, the .357 mag is probably the way to go for HD. (Again, with hollowpoints.)
Read the book: "The Concealed Handgun Manual: How to Chose, Carry, and Shoot a Gun in Self Defense" by Chris Bird. He talks a lot about what happens AFTER you've shot someone. You don't want to be worrying about hitting your next-door neighbor's house or CHILD while the cops are trying to make a case against you for shooting the perp. Hope to God that your bullet(s) don't leave your house, or hit the ground if they do.
