Why use a gun chambered in 6.5cm, 308win, 300wm, or 338lapua for home defense, unless you mean defense of your large estate and need long range? Shotguns are long and unwieldy. I’d go for hand guns with rounds that distort when they hit something so there is less chance of penetration and continuing on. Most likely 22lr or 9mm. 22 has less stopping power, but usually more capacity.
