You can't beat the SKS for cheap, cheap and effective ammo and compact an light for defensive in surplus. Everything later is select fire and unaffordable. Get it now, and add a nice 308 bolt rifle later for that long distance target shooting.
I used to love being able to hit hard at 1000 yards. As I get older I find hitting a mini ram at 200 yards with the 22 oddly more satisfying.
