I have done a number of unscientific tests on retired (Old and out of date) ballistic panels (soft body armor) All were level IIA. am guessing I have shot up about four or five different vests over the years. I have soaked them in water, left them in the sun and weather for months and left them out in freezing weather. I have never shot one with any handgun or a shotgun round that completely penetrated any one single panel. I am talking 12 gauge 3" copper solids, one ounce slugs, 44 mag, 357 mag., 357 sig, 50 AI (Desert Eagle) 22 mag, 22 LR and 17 HMR. and many others. I even put a panel on muddy as well as hard ground and fired slugs at point blank range with no complete penetration. On the muddy ground the slug balled the vest up into a ball and drove it about three to four inches in the mud.
Significant non rimfire rifle rounds blow through soft armor like nothing, front and rear panels to be exact.
I think soft armor panels are somewhat factory under rated with a built in safety factor as to their actual stopping ability. In short soft armor works quite well IMO. It is not perfect by any means but it sure as heck beats nothing! As we all just tragically saw in Indpls. side protection is limited. It also has many other protective benefits other than gunfire.
