I was working on that last night as well, doing tons better now that I am finally paying attention to the bloom!
It's been brought up before, but at a distance, crouch. The accuracy increase for all weapons with bloom is insane, and because you stand up the instant you get hit, it's not much of a risk to use.
You can nearly spam the trigger on the DMR and stay laser accurate, can do exactly that with the NR, and the Magnum and AR become a lot more usable on targets at a distance (still need to burst fire the AR, but that's always true - it just recenters much, much faster)
edit: important, almost forgot - when scoping, the accuracy is basically increased by whatever the zoom multiplier is, so you're
always more accurate while scoped
So crouched and scoped is your best bet for nailing long range kills.
Crouch: Retain more of your accuracy per shot, and recover lost accuracy more quickly, enabling faster firing.
Zoom: Shoot with more base accuracy, standing or crouching.
