After seeing the poor results of the .380 ACP Pow'Rball wet pack results, I decided to risk irrate neighbors and do a little "garage range" work with the Pow'Rball in .357 Sig from a KT P-357, and .45 ACP from the Taurus PT-145. Each has roughly a 3.125" barrel.

Here's the results:

The .357 Sig penetrated 15.4 inches and expanded to .625 inches.

The .45 ACP penetrated 12.8 inches and expanded to .76 inches. The "wound cavity" was impressive.

Here is a comparison of the .357 Sig. next to the .45 ACP.

For our P-11 carrying friends, the 9mm+P Pow'Rball results from the P-11 are below:

The 9mm+P (bullet on the right) penetrated 13.2 inches and expanded to .59 inches.
