Primer failure on multiple firearms. - Ammo, Inc. Signature 9mm Luger 115 Grain Total Metal Jacket Brass Cased Centerfire Pistol Ammunition

I bought 500 rounds. Went to the range and shot 100 rounds. Was firing Sig Sauer P320, Sig Sauer P365, Glock 19, and a Smith & Wesson SD9 VE. The strikers or hammers hit the primers, physical deformation on the primer, but the cartridge failed to fire. Thinking one of the guns might have produced a light strike I tried to fire the round in a different gun. Again, the cartridge failed to fire. The Range officer was surprised with how often it occurred. I had 6 rounds, at least one in each pistol magazine fail. I have shot thousands of rounds without fail from other brands.
