Well...here is the good old US of (fast food and McDonald's) A, our criminals can put on a lot more padding! (Especially during the winter with thick old coats). So, I concur, in that .380 FMJ is the way to go.
Here's a good read:
http://smith-wessonforum.com/ammo/98508-380-load-calling-erich.htmlThere's many more discussions on the web.
One addition/correction is in order...
Ace is dependability. (plus one for the CZ83)
Accuracy (IMHO) is KING. (plus another for the CZ83)
And the penetration is Queen. (that's my FMJ arguement)
Rounds that work well with the CZ83?
In my experience, the CZ83 handles just about anything...even Winchester White Box (WWB).
Fiocchi, S&B, Remington, Speer, Carbon, Hornady, factory reloads...no problems.
Buffalo Bore? I wish I could afford some. The 100gr flat nose hard cast would be my carry load. I have no doubt the CZ83 could handle it.
Congrat's on your CZ83 ... Penny for penny, the best purchase on today's market (include the CZ82).
