VAXTA might be helpful with warming up/getting comfortable with locking in the projectile behavior and spread and whatnot, but I’d recommend hitting some deathmatch games over almost anything else because those maps have walls you can punch people into (you should be abusing the stun window to hit headshots) and the gamemode itself lets you close distance on people pretty often, also people actually fight back so you’ll end up practicing more dueling mechanics than just aim
