airsoft uses 6mm bbs. Perhaps you are talking about weight? .20 gram is good.
I would personally buy .25 gram high impact bbs for good precision

Just about any major airsoft retail store. my top picks are airsoft gi and evike but just about any other airsoft website will stock them (unless of course you want tlsfx pyrotechnic grenades, they mainly sell those in GB). Just go on the websites and search "airsoft grenades".
Here are some good websites: airsplat, shortyusa, airsocom, toysarsenal, and mr. airsoft. Those are some good websites if you want to gget quality guns that will last. Most of those sites are American, try www.mach1airsoft.com for Canadian good quality guns.
Some good airsoft websites are AirRattle, Airsoft Station , Evike , Airsoft Megastore , , Airsoft Atlanta , Airplat , AirsoftGI , ShortyUSA , Renagade Airsoft , Trinity Airsoft , Godfather Airsoft , Airsoft Outlet and Airsoft North West, airsplat.
Probably the ump45, its fast and comes with good amount of ammo, quick, decent attachments and can shoot down uavs with a breeze.

niether Nerf is for kids and they have no distance. get and airsoft gun or at least a rubber band gun. the band gun is good because it doesnt hurt they're lighter and have more ammo and longer range. i very highly suggest the airsoft because they can have so much more ammo than a stupid Nerf, but were gogles with airsoft they can cause eye damage if you get shot and they are soooooo much more fun
eBay and Amazon are a good place to start. However, should one not find some, one should check the websites ReplicaAirguns, Airsoft Atlanta, and AirgunDepot.
As much as you can carry. You want to have enough ammunition to make sure you don't run out before the war finishes. A man is only as good as his weapon, and his weapon is only as good as it's ammo. I would recommend, first of all, a pair of pants with deep pockets, and 1200+ rounds.
