How do you have hardly any wobble looking through your scope? My rifle and shotgun perks are maxed and still doesn't look anything like your stability. I've almost deleted the game because of the up and down bullsht my scope does even when doing a breathe hold
Have you put any perk points into archery? The second archery perk helps with wobble. But so does your stance. In this video I was prone, which decreases it a lot. I usually at least crouch for most of my shots. Hope this helps.
