Two totally different actions. The Bighorn will have much smoother and easier bolt lift, and has the advantage of a floating bolt head. Badger will be a much heavier and stouter action, not that the Bighorn is flimsy by any means. It's a 3 lug design, and if you are out to use AW mags should feed from the more reliably. Neither action will have an advantage over the other in terms of what kind of groups they can produce, the barrel and the shooter will determine that.
