Just picked up a 350 legend AR "pistol" a couple weeks ago, ballistics look good for what it is. Anyone ever shot an elk with it? I planned on using it with iron sights as a brush/under the seat in the pick up gun. Ive seen plenty of videos of deer being shot with it but am wondering about elk under 200 yards. If you have experience with it which bullet/factory ammo worked for you, Ive bought a plethera of factory ammo atleast what I could find to be available.
