One of the best visual representations of what various bullet types do in ballistic gelatin can be viewed in slow motion at
High Speed Video.
Solids in general are poor self defense rounds, they can work but they are far from the best choice. Watch the slow motion video of the .38 spl Federal wad cutter from a snub nose and compare it to the .380 solid round nose or the PMC JHP along with the 9x18 Silver bera JHP that fialed to expand. You will see essentially no difference in performance. Then compare it to the . 38 spl 135gr Gold Dot and the 110gr +P+ treasury load and any of the other JHP's in .380 acp, 9mm or .357 mag.
If you still think solid non expanding bullets are the way to go then so be it.
