Step 1: Get a gun & ammo!
1. Get a rifle, shotgun, or machine gun ranging from 250-350 fps unless you are a sniper, in witch case the fps should be above 400.
2. Get a secondary weapon such as a pistol or mini automatic ranging from 225-300 fps. ALWAYS HAVE IT READY TO USE!!!
3. Get a pourable ammo container with at least 2000 bbs. If you have a non-pourable container use a drinking bottle of some sort.
