I would like to see the individual who could take a slug in the chest, at 50 yards or less and be able to function in an effective way, even with a vest. Just saying what a huge impact...
Yeah, in the case of the Truball it will have about 400 ft/lbs more energy than the 5.56 round. If we're talking soft armor the backface deformation would probably be severe, not sure how much as the NIJ doesn't test 12ga as part of the rating although I've never seen a Level IIIa that wouldn't stop 12ga. If we're talking a ceramic/PE plate you'll notice it but you're unlikely to suffer any injury; they're made to stop a lot sterner stuff.
Apropos of nothing if we're talking defense against humans I can't fathom why a person would go with a slug vs buckshot of some type. Especially for home defense! The big advantage that folks generally tout of the shotgun is the multiple projectiles causing multiple wound tracks, the higher percentage chance of scoring a hit and the decreased penetration. Slugs negate all of those advantages leaving you with a low capacity "rifle" with punishing recoil, slow follow-up shots and vast capacity to overpenetrate common building materials. A 1oz fosters slug has a pretty good chance of going completely through a typical house or apartment, at least if it doesn't hit the water heater, etc. For HD I'd much rather go with Flight Control 00 Buckshot for the 12ga. When hiking or camping it's slugs all the time though; even the largest buckshot might not penetrate a 900 lb bear deeply enough to bring it down before it wrecks you.
