Tends to missfire - STV Scorpio 9mm Luger 124 grain Full Metal Jacket Brass Casing Centerfire Pistol Ammunition

I bought 4 boxes on sale, and every box contains at least one bullet that doesn't fire.
I wouldn't recommend it. This is the only type of ammunition that causes problems with my gun.
Also, I noticed that the barrel is very dirty after each use of this ammunition.
All things considered, few cents less per round is not worth all the cons.
First and last time I experimented with this.
