Eons ago, vest wise, there was a fellow who made vests. He had several folks with different caliber handguns shoot the vest while he was wearing it (talk about faith in your product). Even then, they would stop the rounds they were rated for. You will notice he did not offer to let someone shoot him with, say, a 30-06. The vests weren't rated for that, and he was not a stupid man.
The OP posted about .22lr, not centerfire rifles, or 5.7's or anything else. And he wasn't posting about shooting "around" the vest". I figure we've pretty much determined that the folks who think a .22lr can penetrate a proper vest need to read a bit, and learn some things from that reading.
