Controlling your recoil:

1. If a target is far away and his hitboxes are obscured by cover, fire in single shots preferably .4 seconds apart or more, preferably at his head.
2. If a target is exposed and far away, you can burst at the target. But not recommended, however you will likely be able to bring your recoil down to normal (ie. at ready position) within 2-3 seconds.
3. If you need to spray at a target (medium to close range, say 40m or less, less being preferable), then it depends on weapon. Certain rifles are better at spraying than others, but in a general sense, you need to watch where each bullet hits and start adjusting. Pros (or whatever) tell you to aim lower, because that adjusts the recoil firing up the most while you can strafe left and right while turning to direct the bullets.
4. Recoil can be reset by simply not moving for 3-4 seconds. You can reduce recoil by crouching.
5. You can also tap your fire key to fire relatively straight with any rifle for the first several shots (like around 4). Of course this depends on how much time you give inbetween each tap, basically its the same as shooting single shots, except much more effective with guns like the AK and colt, vs gali and famas.

When to reload:

1. When you are safe. Ie. Hear nothing, know nothing is nearby, and have checked the radar so you are in a good position. (and behind cover).
2. When your teammates are taking point and shiz.
3. It only takes 4 bullets to kill people in most cases, dont bother to reload in close firefights or in hectic situations unless you are planning to spray at the next thing you see and trust your primary gun more than your pistol.
4. When you hear other people retreating and reloading.
