Well after much hunting and realization you either have to go with expansion or adequate penetration in .380 I stumbled across this product from Winchester:
It has a brass enclosed base to stop erosion from the lead core and designed for indoor ranges, however that's not why I am interested in it. It appears to me that it looks like a jacketed soft point round with an exposed lead flat nose...brass jacket.
This should provide a limited mushroom and adequate penetration (12"+) in my opinion. Has anyone ever tested this round for penetration or expansion?
Remington also offer a similar type but it appears the nose is more rounded:
So are there any experiences with this round as a defensive round or any ballistic tests floating around on the internet?
