Backblast:

Tghe newer rounds with the stuff be it salt water or iron dust etc may reduce the damage for someone in the backblast, but it will still put them out of action for a few moments giving them what amounts to stun damage.



As for the whole armor piercing thing:

Remember, alot of the markings on special ammunition is common and standard throughout NATO. I actualy had it in my magic book of knowledge that all good NCOs carried. And it was designed not just with common lettering but also with specific colors <colours for you European peoples> so that even if you didn't understand the language you could tell what type of round it was by the colored markings.

As or special ammo for small arms. I would usualy give it some kind of benefit like with incidiary it would give a chance per round to catch something combustible alight. For ammo since most modern small arms rifle ammo is steel core 5.56 had no special rounds, or all of it was however you want to say it.

Hollowpoint, would have moderate penetration value but I'd toss an extra dice for wounds.

As for something like 7.62 I never really included it as the round itself was pretty powerful as it was, and from personal experience I have seen 8mm and 7.62X54 go through sizeable pieces of steel and most target a belt fed 7.62 or 8mm or 30-06 round hit well for the most part the round would penetrate easily or not at all. Think about it, hitting a light vehicle it would penetrate easily, on a tank or armored vehicle however, it would have little effect.
