Or another idea on the ammo side would be let everyone load up before the game however once the game starts no matter what the use of bb loaders of any type is prohibited. That way you have to take the time to load your magazines by hand which is a pain in the ass and will discourage the spray n pray personalities.
And I'd have to agree with sha do on sniping. I will only run heavyweights in my BA seeing using lighter weight bb's dont quite cut it. In real war situations snipers use match grade ammo and not the regular stuff grunts use so would be nice to reflect on that part.
If I was banging all of them, I'd be a manwhore. At the moment, I'm just an opportunist.
