I can see that thread being looked at positively for different reasons. Were you making a specific point by posting it?
Otherwise, DocGKR does make the case that 9mm FMJ is more effective than 380 FMJ IF
anything more than flesh was encountered like bone or an intermediate barrier.
And of course he goes on to add that 9mm JHP is leaps and bounds better than 380 JHP.
And that he'ld never willingly carry 380 in any form over 9mm in any form.
The most interesting thing I took from it (which I agree with) is where DocGKR says; 9 mm M882 ball has one of the worst reputations for effectiveness of any 9 mm ammo.
The reason I bring that up is because we have a good handful of GTers who insist on carrying 9mm ball/FMJ.
Again, what was it you specifically found interesting?
