How do you 360 or 180 no-scope in call of duty 4?

How do you 360 or 180 no-scope in Call of Duty 4? If you actually know what this means then you'd be a big help.

Here is how to do it:

1. Create a class with the first sniper, (M40A1) with the perks
* 1.Bandolier (so you have more bullets for the sniper when you begin because bolted snipers don't have a lot of ammo to begin with.)
* 2.Stopping Power (for that one shot kill.)
* 3.Steady Aim (to increase hip-fire accuracy the whole idea of no scoping.)
2. Use the first sniper because to be known as a good no scoper you have to use a bolted sniper. The M40A1, was selected over the R700 because of its bullet capacity. The M40A1 can hold five bullets where as the R700 holds four bullets. Having more bullets gives you an edge to begin with.
* If possible use the ACOG scope because when used with the M40A3 it adds damage for an unknown reason, so when combined with Stopping Power, the M40A3 can have a one hit kill, no matter where you shoot a person making No Scoping easier.

well to get a 360 you need a lot of practice for finnaly to get the hang of it. and 180 umm im not sure sorry but try to 360 in sensitivty 10 ok go to private and practice with a friend. at first your going to be way off and almost try to give up but dont keeep trying trust me I did and I can say im preety good at it hope it helps and if you need some help just add me my gt is NsK xXGODSXx ok cya and good luck!
