When thinking about home defense, you should consider penetration. A 30-30 will go through a few walls, not good!
The best home defense long gun weapon is a pump action shotgun with #1 buck, or just about any load including #6 or 9 birdshot, devastating at close range. (a famous African hunter decapitated a wounded lion with both barrels at once with his side by side shotgun. He had #9 birdshot in the tube).
If you must have a lever gun, 45Colt in a Winchester '94 trapper, or Marlin is my first choice. Big, fat, slow moving heavy bullet will put intruders down, and less likely to kill your neighbors child in the next apartment or house.
