I do know for a fact that a 95gr Federal FMJ penetrated about 12" of possum, right through it's forehead, exit below chin, re-entry near sternum. The bullet exited again very near it's tail, from about 15' away. About 5 minutes later it attacked the shovel I was using to bury it, requiring BFT to dispatch it.
I lost faith in .380 for anything but a last resort.[ I think I have posted my one use of a 380 here before. Cold January day walking my dog and a pit bull came under a chain link fence and attacked both of us. By the time I could get my Colt pony out I was rolling in the mud I was bitten on the face ,hands and legs and my dog mauled badly.One shot into the pits left front shoulder with silvertips contact distance and the gun jammed and the dog ran off.After trips to the Vet my dog had to be put down , then the E.R. for me police finally arrived and dude said he didnt know where his dog was. Animal Control picked it up the next day he had hidden it in his closet. I had to i.d. the dog and aside from the hole and some bleeding the dog acted like nothing was wrong. Changed to 38 subby with 158 grain hard cast after that. No trust in 380 now.
