Novice user - Magtech 9mm Luger 147 Grain Subsonic Full Metal Jacket Flat Brass Cased Pistol Ammunition

Don't really have much to say about this item other than I usually always purchase Magtech brand. Probably because I read they were very clean firing. I don't go shooting often, I'm more of a "prepper" or "what if" guy. I have thousands of rounds of 9mm Magtech in all different grains and points. I didn't even realize these were flat points - thought they were hollow points. I purchased these because they were on clearance sale and I noticed I didn't have many or any 147 grain. I will use them in my 9mm Ruger P89DC.
