Defender Rubber Balls 43 Caliber, Black

I bought these rounds for target practice and they're pretty good for that but I don't recommend them for self defense purposes

These are fine for shooting and obviously any projectile with enough kinetic energy can inflict pain but i was expecting something heavier and harder. These arent too much heavier or harder than the 11mm police training red markers ive been firing since getting my .43 s&w. Granted those two rounds are all i have fired so i cant say for sure that another type of ammunition like steel rubber balls or pvs coated steel etc are better but i dont see how they couldnt. I actually had to shoot a racoon jn the face from 7 ft away last night and he yelped and ran off which is less than self self defense but if a big rat with opposible doesnt even meed a doctor after getting hit in the face close range what kind of effect do u expect when shooting at a fully grown armed human being in a for of extreme anger or on drugs committed to doing u harm? Get something heavier and not quite as soft or pay the price when the tome comes
