At the risk of starting a 9mm vs. 40cal debate (which I'm really hoping to avoid), is there enough data to suggest that 40cal FMJ is a better defensive round than JHP?
This can also be spun as an expansion vs. penetration question. FMJ has the penetration of 18+ inches, but lacks the expansion and subsequent wound-channel of a JHP. The JHP obviously has the expansion, but from the majority of ballistic tests I've seen, penetration is around the 10-12" mark...well short of the accepted 18". With cold weather and thick clothing being the norm this time of year...
is FMJ better than JHP?
As always, my thanks to for THR! And please...don't turn tell me to sell my 40 and buy a 9
