This is the default sorting, which you can get back by clicking the top of the "AMMO" column. You can see the first offering, Magtech First Defense, 124gr bonded JHP, clearly didn't expand. The 5 shot average diameter is 0.35, which is almost textbook 9mm (.356"), and the average depth into gel was 31.5"! Clearly over-penetrating - unless maybe if you're being attacked by Sumo wrestlers. By contrast, the next listing, Black Hills 115gr +P expanded to 0.69" and penetrated a much more reasonable 13.76".
The test results are on these four web pages, which also feature the ability to look up each round and buy some:
details on the test setups are not on the results page, so it took a bit of digging to find this:
We fired each round included in our testing from a distance of ten feet, following the FBI standard, measuring from the muzzle to the front of the block.The data set is hours of entertainment for the "numerically inclined" and you can bet any amount you'd care to bet that people will bitch about it because it didn't test their favorite ammo, or their favorite gun, or something. It may have me picking out a new carry round for my Sig P238, though. The Speer Gold Dots I've been carrying apparently didn't expand in their test. Some more research is in order.
For our condensed version of the FBI test we opted to simulate shooting through typical heavy cold weather clothing as our intermediate barrier. We placed the barrier in front of the gel, which consisted of one layer of Denim (14.4 ounces/yard), one layer of Polartec 200 fleece, one layer of cotton dress shirt (3.5 ounces/yard) and one layer of cotton T-shirt material (5.25 ounces/yard).
