I have seen quite a few different gel tests of different ammunition choices and calibers. I have seen a lot of seemingly reliable ammunition choices cloth and not expand. Here is my big argument. Everyone uses 4 layers of heavy denim. Denim is a very heavy weight fabric that is tightly woven and durable. Who do you know wears 4 layers of denim over their torso? I would like to see some modern clothing in these tests. Let's say a t-shirt and a nice thick North Face jacket. I believe these bullets would perform differently. I think clothing tests should be using multiple fabrics. With bare gel test, one of the best .380 performers is the classic Hydra-Shock. But denim tends to clog it all up. Anyone else ever think about this?
