Archangel, I know you are well versed on many subjects and we agree that too often a thread wanders off course without addressing or ignoring the original question.
As you might agree, sometimes the answer is so obvious one may wonder why the question was asked in the first place. Other times the question raises other questions and needs qualifiers to answer it and this is where many threads start to wander.
To respond to your statement...
I can't understand why everyone can't just answer the question instead of changing the thread into something the OP didn't ask about???
( No flame intended)
The question of 380
preferred weight can be easily deduced by most people by looking at the offerings available on your LGS shelf and thus no question would be needed. Most manufacturers offer only 90 & 95 grain (with a couple 88, 100) so it would seem most users would prefer one of those two weights. Take your pick. End of story.
However, Since I don't see many 90 FMJ nor 95 JHP offered, the design of the bullet must have something to do with the selection... I might then wonder which is better and why? Also the question of which is
preferred opens up the question to include 'why'. Ah, now there is an opportunity for subjective discussion and while we're at it lets consider some of the odd ball specialty offerings. Maybe, with more information a conclusion can be formed. Thus the roll downhill to the FMJ vs JHP debate.
Like many, I have had to consider that question. Expansion vs penetration, light & fast or slow & heavy etc. (and we all are assuming on having good shot placement when it really counts). That is why I offered the suggestion of a 95JSP (same weight as common 95FMJ but potentially better expansion), a 100FMJ (more is better, right?) and the 102 GS (heavy & JHP- whats not to like?).
alas, we will never escape the commercials, our only salvation is the off switch.
good shooting
