SigFTW, thank you for looking and for the compliment but it's important to note that my tests are informal, not performed to laboratory standards, and most importantly, I only conduct one shot. Most professionals advise at least five shots as a statistically relevant sample size.
This load performs much more poorly through auto glass. That might seem like no big deal until you consider how much time we spend around cars.
9 mm Corbon 100 gr +P PowerBall 1555 f/s from G17
BG: pen=10.9”, RD=0.60”, RW=93.9gr
4LD: pen=11.4”, RD=0.58”, RW=97.5gr
The mighty 4.7” of pen after the auto windshield was not comforting…
The frequent core-jacket separations and rounded leading edges of the PB
loads are a concern, as is their poor terminal performance after intermediate
barrier penetration. We were frankly unimpressed with these loads. If you
have to use Corbon handgun loads, stick with their DPX loadings of the
superb Barnes XPB all copper bullets.

The performance through four layers of denim in Dr. Roberts' test was about an inch and a half less than in my own test. That is likely within the normal variation for this bullet and not an indictment of my test protocol but if there is an error, it would be with my test and not his.
It's also worth noting that the reason Pow'RBall tends to penetrate more deeply than is typical for a modern JHP in the same weight, is that the polymer ball delays expansion so for the first few inches, the bullet acts just like ball ammo. That means that in a frontal chest shot, the bullet could have passed the heart or major blood vessels before it even begins to expand and that means that incapacitation through blood loss is likely to take MUCH longer.
It looks as though you live in TX so you are not constrained by any ridiculous restrictions on bullet type. If your chosen carry gun does not reliably cycle JHP, I suggest there is a larger problem that you need to address because it may fail you with other types of ammo. Currently, the best carry loads for 9mm are 124 gr HST, Gold Dot, or Ranger T, in that order, with a very slight edge to Gold Dot for barriers. Everything else is WAY behind.
I just had to share this quote from the thread I linked above:
Of interest ONLY. A good buddy of mine has shot more the one deer with .45 power ball. It seems to work ok for that application. I am 100% tracking that in no way does this privide any real solid and usefull data. I don't remmeber if those particualar deer were driving in a car or not.:D
