I hate doing that. Second scoping is my biggest pet peeve when sniping.If u wanna become better in sniper then wait for other sniper to aim when a sniper aim. They slow down which makes it a bit easy
I usually aim for snipers first. I sometimes go on a trade server and my aim is spot on.You're aim is far too finicky, you need to chill, I suggest get some music to play while snipping. Take this tip from another sniper main. Also aim for warden or a medic first, then snipers and then any other class. Save scout for last.
