Fired 150 Rounds of 9mm in 3 different guns today. Here's my take on 2 different brands and 2 different types. 1- Federal Champion 115 grain FMJ RN = decent accuracy- feeds reliable - The most DIRTY Shooting 9MM I have ever shot. Will not buy it again [AR9 ] 2- Winchester White Box Range Pack 115 Grain FMJ = Shoots accurate- Feeds reliable- and shoots Much CLEANER than the Federal. [AR9 and SIG P320] 3- Winchester PDX Defender +P 124 Grain BJHP = Shoots accurate - Feeds reliable - and shoots much CLEANER than the Federal Champion [SIG P320 ] This ammo may perform differently in your 9 MM guns.
