It's late, but I wanted to share results of some testing I did today.
Short version:
Clear Ballistics FBI block (16 x 6 x 6).
With penetration measurements
Equipment used
Block and camera setup
It was meant initially as a G42 380 ammunition test with 9mm Speer Gold Dot 124gr +P through different length barrels as the control.
Conclusions:

It was meant initially as a G42 380 ammunition test with 9mm Speer Gold Dot 124gr +P through different length barrels as the control.
Conclusions:
- To get 380 to penetrate adequately, the trade off is teeny bullets without much expansion.
- Speer Gold Dots are interesting. It seems like the higher velocity initial impact, the more the petals are forced outwards which leads to a larger surface area but the trade off of reduced penetration. There is a distinct difference to how the Gold Dots looked when shot through different length barrels.
- I was surprised at the marked difference in size of a JHP 380 vs 9mm. It's pronounced enough that I think I might start carrying my G26 again instead of the G42....
