Are you referring to the WWB target rounds?
I would guess so--I've only seen them referenced in a ballistics test, as I don't own a .380 ACP pistol myself.
Manco, Bersa says that the end user should use only ammo loaded to the SAAMI standard rating. So do most other manufacturers.
That would be my recommendation, as well. Fortunately Buffalo Bore makes a line of hot yet standard-pressure .380 ACP ammunition:

I don't usually recommend extra-hot loads or +P loads, but in a caliber that some would consider marginal, I thought that some people would be interested. The only +P loads that I ever actually recommend for defense against humans are in .38 Special because modern revolvers and .357 Magnums can easily handle them, and .22 LR because it can make a big difference in effectiveness in some guns. With .380 ACP (and most every other caliber), I'd stick with standard pressure only, myself.
So any use of Buffalo Bore ammo should be kept to the minimum necesary to ensure function and proper handling.
That would be prudent, as well as more affordable.
So you can shoot through multiple bad guys?
That is not my intention. Although I use and make reference to ballistics gelatin tests all the time, I never take the test results completely at face value. They give you an idea of the relative penetration capabilities of different loads in soft media that supposedly simulates living flesh, but real human beings are more elastic and not so homogeneous. For example, penetrating an arm before penetrating the torso--which is a big deal because arms are often in the way of the COM--involves penetrating multiple layers of skin, which tends to reduce actual penetration by several inches. This is because skin is more difficult to penetrate than muscle or calibrated gelatin. And bone and sinew, of course, can reduce penetration rather significantly.
If we add the large size of certain individuals to the equation, as well as bullets sometimes striking at odd angles in real shootings, then 10" of penetration seems rather marginal at best to me. Sure, it's enough to kill, but then again so is a .22 Short, and I wouldn't recommend either. Penetration is second in importance only to shot placement, and actually enables shot placement, so I would prefer to have a greater margin in that aspect of terminal ballistics over a wider bullet. It doesn't have to be as much as 20"--I only used that figure because that's what .380 ACP FMJ gives you, and I'll take it over 10" and an expanding bullet. Some loads, namely Federal Hydra-Shok, get about 12" with less expansion, and are also worthy of consideration, but I still like 20" better, personally.
Take a look at the new Winchester PDX1 95gr. JHP
Does anybody have terminal ballistics test results for this load? I'm not fond of the Winchester Ranger-T .380 ACP load because of its poor penetration (less than 8"
), but the bonded versions (i.e. PDX1) sometimes perform very differently, so the jury is still out, in my opinion. My .40 S&W defensive load happens to be PDX1, but I don't consider myself biased in any way because effectiveness relative to caliber for all product lines depends on the individual load and sometimes on the gun they're used in.
