32 fmj vs 380 fmj vs 9mm fmj
This is a discussion on 32 fmj vs 380 fmj vs 9mm fmj within the Defensive Ammunition & Ballistics forums, part of the Defensive Carry Discussions category; Just curious how much of a ballistic difference there is between the three calibers as far as strictly fmj goes...from 3" barrel or less....

There's quite a bit of difference here. Not sure what size barrels were used for these, but here are some data from Ballistics 101
71 gr - 900 fps - 128 ft/lbs of energy
95 gr - 980 fps - 203 ft/lbs of energy
124 gr - 1150 fps - 364 ft/lbs of energy
In the 9mm, you probably could not find a worse defensive load than FMJ (unless it's shot capsules). The NYPD had several documented cases of bystanders being injured or killed by 9mm FMJ rounds penetrating through the target and striking the bystander.
In general, FMJ is a poor choice in defensive ammo, but particularly so in 9mm.

I use fmj in 32 and 380 for the sake of penetration but would not use it in 9mm as stated by Matt...

Personally I'd opt for the Flat nosed FMJs if that's what you are going to run... Better FPE and a straighter wound path with slightly less depth penetration comparatively. In 9mm, no reason to use FMJs for defense, in fact, IMO it boarders on recklessness for that round and up. JMO

I think your .380 ballistics are a bit optimistic, standard .380 round is a 90 grain bullet that really does 800-900 fps depending on gun/barrel length.

What information lead you to this opinion? I am simply curious as I have never heard this before.
