You do realize that All Modern Assault Rifles have greater effective ranges than the piddly range listed in Shadowrun with lower FPS than you are spouting at the muzzle right? Hell, as a Marine you qualify at 500 meters with the M16/M4, which should tell you that the Ranges for weapons in Shadowrun are not really accurate at all...
And, in 60 Years, who knows what kind of weapons we will have (I would be willing to bet that you are not a weapons designer for the Government)... Physics may not change, but weapons sure will, you can bet on that...
Greater ranges? Not really. Marines qualify at 500 yards, which is actually only 457m. The effective range of an M16 with the 20 inch barrel is actually 550m for a point target, which is likely why they chose that number when they wrote the rules for the game. Can they shoot farther than that? Sure. Could you even hit targets farther than that? Sure. But even scoring hits at 550m is pretty difficult. An AK-47 only has an effective range of around 3-400m. So if there was going to be an arbitrary number assigned to assault rifles, 550m seems acceptable and hardly piddly.
Oh, and 2800-3200 fps is the muzzle velocity for a 20 inch barrel 5.56 rifle depending on ammunition type. If you drop too much lower than that, effective ranges will drop as well. For example, part of the AK47s lower effective range comes from its muzzle velocities closer to 2400 fps firing a slightly heavier round.
Sure, for Shadowrun, the ranges are probably a little on the low side. With the developments of new and better calibers and propellants, I doubt 5.56N will the standard rifle cartridge in 60 years. However, despite better ballistics, the weak point of every weapon is the man firing it. And at 550m, a person is a pretty small target to hit. So even with a better, flatter trajectory round like, say 6.5 Grendel or the like, you're really not going to increase range too significantly for battlefield applications. It's still a small round and at the mercy of the wind. So if they were going to choose an arbitrary maximum range for assault rifles, 550m isn't terrible. Nobody should really be engaging at that range anyway. Even for a skilled marksman that's a hell of a shot with any cartridge on anything but a stationary target.
