How can it be faster to shoot 50 rounds with the MP7 when compared with P90 since the MP7 has a magazine of only 30 rounds and the P90 50? Also, I'm pretty sure that I can hit a target at 333ft away with a P90.
I must have missed your second point (or you edited it in). The maximum range for the P90 is 3700 in-game units (308ft) compared with 4000 units (333ft), so you cannot!
That said, very few places in any official CS map have ranges that long. One would be on Train from Terrorist spawn to "Ivy" @ 3900 units (325ft).
The rounds fired value is limited by the number of bullets in the clip, so you can select up to 50 rounds (because the P90 is in the comparison) but the MP7 will run out of ammo at 30.
