Really hard time feeding - PMC Bronze Ammunition .40 S&W 165 Grain Full Metal Jacket Brass Casing Centerfire Pistol Ammunition

For some reason, about 40% of this ammo I have jams on me, and I have to manually clear the slide. I tried cleaning my pistol and it had the same problem. I tried some Federal 180gr, and it worked perfectly fine 50 times in a row. Sadly a waste of money for the Glock 35 and 29.
