My focus/crosshair will be on someone and my shots whiff

yo, console player kinda seeking some tips for gunfights, ive been playing and have recently noticed how when using the vandal/ phantom, or any gun, the bloom gets too bad and i end up dying.
Ive gotten used to stopping and usually crouching in my gunfights now, and it's really the only thing im missing (besides my shots)

thanks slimes
