Nice to see an old dead thread that still has a lot of relevance be resurrected...
Although my experience with .380s goes back to the late 1970s I naver carried one until recently. I used to be a commercial loader/reloader and made an identical round to wath CorBon now sells as their 90 grain +P JHP with the Sierra bullet. Found several hundred rounds that had never sold back in 2014 and ended up buying a Kahr P380 to just shoot them up in.
Was so pleased with the combination it replaced the KelTec 32 I had been carrying when carrying a standard size gun was impossible/impractical.
Carried the 90 grain load for a couple of years until I saw a video on the Underwood ammo with the Lehigh fluted solid copper bullets at significantly higher velocity and now use that ammo.
So what is everyone else using now...still ball?
