4-layer denim represents the toughest soft intermediate barrier. 2 layers of denim is still very difficult, as is basic t-shirt material. Clothing causes older JHPs to clog up and act like FMJ. The issue is back when the test was done, none of the JHPs were designed to defeat soft intermediate barriers, so thats why wadcutters with sharp shoulders were advocated. Its no longer an issue with the previously mentioned JHPs that are designed with soft barriers in mind.
