I have a thread going...
.45 ACP bullet-expansion test results
...on .45ACP ammo expansion testing. I hope you find it worth your time.

I hate to rain on your parade, but such testing is worthless and provides zero correlation to how bullets work (or don't work) in a living human being.

I totally agree.....The man needs volunteers!

CTG, you may be essentially correct, but I'll write it again--I'd much rather carry a cartridge with a bullet that expands, stays together, and still expands after passing thru thick clothing, than one that clogs with thick clothing and doesn't expand or one that comes apart in waterjugs. My testing methods have been essentially consistent over the years, and I'm VERY comfortable carrying those bullets that perform well in my tests.

And besides, not a single being has volunteered for expansion-testing-in-humans duty, so I don't have any people, or cattle, or hogs, or any other beings to test bullets on.

So you get to carry what you like, and I get to carry what I like, and I'll continue to test bullets and publish results.

If your testing methods give you peace, so be it. There are much more accurate ways to test bullet performance. You also need to examine how quickly bullets expand, and your testing methods don't do that. Too rapid of expansion detracts from penetration. Also, why such light bullets? The best Hornady CD load for 45 ACP appears to be 220 gr. You're kind of hamstringing yourself with such light bullets.

The results of your test are similar (if not identical) to those posted by a couple of youtube channels: Tnoutdoors9 and Scubaoz. I'm guessing you're having a lot of fun doing this, but if its just for the purpose of gathering data, you can save yourself some $$$ by simply checking out their channels.

I lean toward the Hornady line, but Critical DUTY instead of Critical Defense. Their flex tip design for the hollow point cavity reduces to zero the likelihood of failure to expand, where-as I have seen both Federal AND Gold Dot (both GREAT rounds) fail to.
