Winchester needs to step up their quality control. - Winchester USA Handgun 9mm Luger 115 Grain Full Metal Jacket (FMJ) Brass Cased Centerfire Pistol Ammunition

Just had a chance to shoot this ammo at the range. Out of 100 rounds I had 5 light primer strikes. Examining the cartridges the cases are flawed. The rim of the casing appears to be thinner. Tried these 5 rounds multiple times and they would not fire. 5% failure rate not acceptable.
