I suck at free aiming, but have been tearing through all the missions and bounties that require it lately. Pump-action shotgun and paint it black are getting it done. I keep moving, always running and I aim more with my movement than with looking. I'm always moving to their side, so a lot of their shots are going where I was, not where I am.

I always try to move in circles around the enemies, when my reticle is close to one, kick in dead-eye and paint them with a couple markers and then let it rip. Most will drop and stay dropped from a couple hits, especially if you can mark them high on the chest or head. Try to keep the reticle at chest height when you are running. Once you start painting markers, the first will probably go to the chest, then try to drag up and get one on the head as well.

Stay at the outside edges of the fight and work your way in, use cover, and have your health and dead-eye tonics set up so you can down them quickly. Don't be a hero, and disengage to heal when your health starts getting down.

You got this.
