“Have always shot Remington ammo with great performance and no issues. Bought a box of Hornady at Brownells when I first got my 264 mag so I could test the rifle, (Brownells is only 40 miles away and the nearest place to get 264 ammo). Shot a five round group with good results but one of the cases split at the shoulder. Asked ammo salesmen at states largest gun show and all responded, "Defective Brass". Have never had a blow out with any of my Remington factory ammo in 50 years of shooting.”
