I'll try to give u a link to video but for now what you do is move and when your crosshairs stop shoot maby if u want add me PSN Unknownn92 and we can practice shooting each outher. Once you get the hang of it it gets real easy so keep trying.
Don't depend on tricks that people release. That's what helps THEM. Practice with a group of friends and find a technique that works best for you. Once you start beating down on your friends in private parties, start trying it in ranked games. You'll eventually get good as long as you do it a lot.
There are tricks, some more effective than others. as everyone says it takes practice, (and how you use the tricks) in my opinion...
