Your 'reasoning' disagrees with science. It's not reason. It's stupidity.
Religion is a reasoning that disagrees with science too, but thats not always considered stupidity.
Maybe its just my luck, and the guns I've gotten had stuffty ranges (for the low FPSes) and high ranges (for the higher FPSes)
I guess I can be proven against my own reasoning, because my AK47 actually has a superior range than my P90, and they have the same FPSes.
