It was and is a good cartridge, but it's not "a short-chamber, Boxer Henry .45 calibre miracle."

If the differences are that unappreciable in real life, then in the game they're going to mean even less.

Yeah, but the M249 has longer barrel so it should have greater muzzle velocity shouldn't it?

So why is it so weak ingame?.

Start providing sources for what you are stating.

No it doesn't. The M249/FN Minimi in standard configuration has a barrel length of 465mm linky where as the M16A2 has a barrel length of 508mm linky.

Additionally, what affects stopping power is energy transfer. And thats complicated and when you get into differences between rounds its not just velocity and weight. You have to take into account if the rounds tumble, fragment or expand, how much energy the round still has when it overpenetrates (as most of the rounds being discussed here will pass right through a human), what effect armour has upon the round, what effect what else the soldier is wearing has on the round (IIRC some time ago there was a Turkish study which showed that soldiers who were shot in the chest while wearing chest rigs with magazines in were generally injured more badly), what type of round it is, etc.

In short there are far too many variables in play to make any meaningful "realistic" system.

For more information I suggest this article.

Yea don't test most of the developers, alot of them have experience with different guns.

Also, do IRL insurgents use those kinds of weapons? WW2 weapons?

Yes, some of the things they find in weapons caches could do well at auction if they were in better condition.

[Edit]Here's two threads on that very subject
