The Hornady Superformance .308 Winchester 150 Grain Super Shock Tip Centerfire Rifle Ammunition could be used in an AR10. This is what Hornady states in regards to the Superformance line of ammo in gas operated firearms. "Superformance ammunition is safely within SAAMI pressure guidelines. Gas operated firearms are perfectly safe to use with Superformance ammunition. However, we have conducted tests and conclude that some systems work far better than others."
