I've read the merged thread regarding mixing FMJ and JHP rounds but it didn't cover my particular question. As a rule I carry (in my defensive mags) a mix of alternating standard loads and +P loads (both JHP). The theory behind this is that +P rounds have greater muzzle velocity, thus greater penetration. All my pistols are good makes, but none advocate the use of +P ammo, at least on a regular basis. My question is, would fellow forum members recommend my use of carry or advise the use of all standard rounds as +P isn't going to make much more of a difference in stopping a threat.
On a related note, I was suprised to read that some members pack a % of FMJs into their magazines due to their ballistic characteristics. Does anyone know of the legal implications of over-penetration if these rounds were used in a defensive situation? It was once the opinion of the masses (including the courts) that JHPs were "tools of the devil" due to their greater wound channeling, etc.
