It’s hard to explain how I snipe because it’s just instinct at this point. I do spend very little time scoped in. The longer you stay scoped, the more bounce that you get. So, you want to identify the target, scope, fire. It should only take a second.
If you scope and don’t have a good shot then unscope, move, and try again. The longer you stay scoped trying to find the shot the more you’ll bounce.
Speed is the key to becoming a good sniper. L1 is an auto aim so trust it to get you close, then a quick adjustment, and boom. Don’t sit there and line up the shot, confirm you got the shot, and then shoot. Line the guy up and pull the trigger the second he’s in the crosshairs.
Once you get that speed-snipe down you can have the freedom to go anywhere with a sniper.
