Well considering REAL guns use generalized ammo, it's good to have up to a point. A good example would be making SMGs and Pistols use the same ammo (as in real life), and making sniper rifles and assault rifles use the same ammo (again, IRL).
This is for most games, by the way. You can get more specific with, like, 5.56, 7.62, 9mm, .45, .50bmg etc in certain games and it's fun, but for MOST games general ammo is a relatively good idea. A lot better than games like CoD, where you will always end up using the same gun as the enemies, despite 5.56 being used in a shitton of weapons.
For the people i pissed off with the 'sniper and assualt rifles use the same round', 7.62x51 NATO. More punch than the 5.56 and thus more useful for killing instead of wounding, because these are video games and we're not aiming to wound the terrorists and russians.
