Hello. I've only tried the "Personal Defense" 9mm version.
This load is a 105-gr. standard pressure load. From a Browning Mk III, it averages 1214 ft/sec. From a Glock 17, it gets 1233 ft/sec.
It has expanded pretty consistently for me in both water and super-saturated newsprint. I have not shot any animals with it nor have I received any reports on its being used for self-protection. It grouped well for me.
I was going to get a recovered bullet from newsprint on the second test but have decided for a frontal shot on a racoon or wild dog/coyote instead. I almost had one a couple weeks ago but I would have been risking my humble hunting camp (Wally World special tent set up for five or so years now - I'm afraid to take it down! I just keep a cot and food in there). Prior to that I had a perfect shot, out fishin', but it was state property and I wouldn't shoot.
The whole scoop is this, IMO: The EFMJ is a good round, but not better than most HP. It expands by virtue of internal function (some say mechanical; I say fluid because of the silicone). It doesn't expand as large as some others I've seen but will do about .55". Its +P is only to get it into the 1100fps range. This is necessary due to the longer bullet and case capacity. A standard pressure 124gr HP will do this speed.
Some good news I found: I snapped a shot at a rabbit chewin' on our wild foodstuffs (raspberries bordering the property and you can't walk anyplace without stepping on wild strawberries). Indiana says I can protect this stuff on my land. Anyway, I don't know if I missed or if it went through and through the rabbit. The rabbit took off at any rate.
I found the EFMJ in a few inches of soil. It had shed most of its jacket and silicone, which is why I suspect I hit the rabbit. However, the small lead base had expanded like a hollowpoint. It was eyeballed at about half and inch. Remember, this was soil, damp, in a septic tank saturation field. Performance in flesh may not be the same.
There are some questions about the .40 raised by police shootings, and I think I put a link in my first report.
Mr. Smith's post about the rabbit reminded me of a 9mm 105 gr EFMJ round I shot into a Fackler box ( 1 of 3 fired) where the jacket split instead of compressing and dropped off along with the silicon cylinder, leaving the lead base to penetrate essentially as a wadcutter. Here the base didn't expand, though the end which struck the backstop did distort slightly. I remember other examples of this type failure occurring in ammolab EFMJ tests back when it was free as well. The other two I shot expanded well if lacking in penetration , but I have to wonder how frequently this sort of failure occurs.
