The soft point.
Hollow point RIFLE ammo is actually not expanding ammo, it's really to make the bullet more stable by moving the center of balance rearward.
The soft point will expand and is intended for hunting. The hollow point is usually used for long rang target shooting.
Since it's basically full metal jacketed ammo, the bullet will not expand, and isn't intended to. It will penetrate more then the soft point.
So, for home defense, use the soft point, but be aware, even it'll shoot completely through the average house. About the only thing that'll stop a rifle bullet is a concrete or brick outer wall.
For the absolute best HD ammo, buy American made SPORTING 7.62x39 ammo.
It's specifically designed to expand even more then the Russian soft point. It does cost more, but for HD that's no problem since you won't need a lot of it.
