Actually,
I do!
I thought the review of the .380s that Shooting the Bull did a while back was pretty intriguing (the stuff goes to 12" but does not overpenetrate and does make a bigger wound cavity than ball), so I bought some for my 1934 Beretta.

.
I found the Polycase Inceptor ARX 56-gr polymer/copper screwtop stuff was actually fairly accurate - about the most accurate of the stuff I shot from this gun. Furthermore, it had virtually no recoil (of course), ejected and operated fine, and gave good velocities and straight-on hits.
First group (of five, benched at 10 yards):
M 1174/S 64.89/D 27.53
Second group:
M 1187/S 101.9.D 36.72
Check out the three lobes of the bullets, clearly visible in the impacts on the target:
Given the results with this stuff in gelatin, I'm going to switch from FMJ (which could certainly overpenetrate) to the Polycase Inceptor ARX 56-gr for carry in the 1934. I need to run it through my LCP and the BDA before I commit there.
