Follow buckshot to the upper-middle thorax/neck, groin or armpits with a slug or two if laying lower than the attacker. That should do it with a .410. New Maverick (Mossberg) 12 gauges are pretty cheap and hold up well. With those, you can follow 00 buck loads with hardened big game slugs to handle just about any likely defense situation.
Muzzle velocity of 3" .410 000 buck (5 pellets) is around 1135 fps. Each of these weighs 70 grains, and is .36" in diameter.
That will not have the perp getting anywhere near your shotgun if you get the pattern centered on him, leather jacket or not.
Slugs are also "interesting"
Remington 87.5 (1/5 oz) grain .410 Slugs Velocity & Energy Muzzle: 1,830 fps & 650 ft./lbs. 50 yards: 1,335 fps & 345 ft./lbs. 100 yards: 1,040 fps & 210 ft./lbs. That's faster than most pistol bullets, and the slug *will* penetrate and expand.
