I recently jumped in to the 9mm side of shooting (having always been a .45 guy), and decided to conduct some informal ballistics tests using 124 gr Gold dots and 127 gr +p+ Ranger T's. I first lined up 8 one-gallon milk jugs which were filled with water, then placed a once-folded denim pants leg in front of the lead jug for use as a barrier material. I then paced off 7 yards, and fired my first Ranger T from my new gen4 G17. The round completely penetrated 6 jugs, exiting the bottom-left corner of jug 6, making recovery impossible. After this, I repeated the same procedure (8 jugs, 4 layers of demin in front, 7 yards) 5 times with nearly the same results (occasionally the bullet would be lost after penetrating the 5th jug), before switching to the Gold Dots. The Gold Dots had exactly the same results. Somewhat perplexed by my findings (or lack thereof) I decided to remove the denim from the front of the jugs. I fired another 3 Ranger T's and 3 Gold dots, which each settled neatly into the bottom of the 3rd jug while looking much like the pictures we've all seen online and in advertisements. The only conclusion I can come up with for the over-penetration of the first rounds I tested is that they simply didn't expand properly through the denim, which is something of a concern. I know this test was very informal, but I was expecting performance better than this considering all the good reports I have heard from shooters about these rounds. Can anyone tell me where I might have gone wrong with my (admittedly) crude tests, or perhaps should I continue my search for a good 9mm home defence round? (And yes, I know that's alot of milk jugs. My wife and I along with my parents and inlaws have been saving them for some time.) Wanna kill these ads? We can help!
