I posted this in my CZ P-07 thread. However, some of you may not follow that thread. So, I reposted the relevant bits for the general public.
. . .I just completed a thorough amatuer expansion test of the Winchester Ranger Bonded 147gr round.
I shot three rounds in to bottles of Bolthouse Farms Blue Goodness. One round was fired high, another in the middle, and the third bullet low. All bullets hit liquid. To make things interesting I placed two layers of medium weight t-shirt and two layers of sweat shirt over the bottles. It represents actual winter wear in my area.
All three rounds did expand. The largest expanded to 9/16ths of an inch. The other two expanded to 7/16ths of an inch. None of the bullets appeared to be clogged. They all penetrated at least 14 inches and came to rest in the final jug.
I noticed that several of the transition holes were oddly shaped. It appeared that two of the bulltets may have turned side ways during penetration. Does that really effect performance? I'm not sure. I do know that the "sideways" holes measured slightly larger than the straight holes at the widest point. I couldn't tell which wound profile would be "better." I just know that they both could be lethal.
My next test was using old plastic ice cream jugs. A friend of mine donated the jugs and tops. His church had used them for easter baskets and had a ton left over. He asked if I wanted them and I said "oh yeah." I filled them up and laid the legs of an old pair of jeans across the front. In my estimation that is for layers of denim. I have only worn the jeans twice so they were still heavy and stiff.
I fired three bullets with the same basic results as the first test. I measured a shortest penetration of 15 and 5/8 inches. The longest was 16 and 3/8 inches. Expansion was roughly .5 inches for every bullet. One bullet was recovered laying sideways in the water.
Then I decided to try a test the FBI doesn't use. I stuffed a milk jug of water in to the cavity in a cinder block. Then I fired two rounds through the block. It looked like the picture of expansion through steel. It was pretty much a round little gnarled ball. It would still be potentially lethal. So, if you ever have to shoot through half a cinder block you should be okay.
