If you search YouTube for “Ammosquared” you will find several tests like this for example:
These tests are where I got the data for my chart.
I took seven of each of the listed ammunition sources and compared them head to head in the included chart. I apologize if my writing is hard to read. I originally did this chart just for myself, and then realized, I should share it with the Glock talk community. I appreciate being a member of this community and how other people are so willing to research and share things. These are very well done in my opinion, ransome rest tests, at 25 yards that demonstrate some interesting observations. There was not always a clear winner with one generation over the other but on average there was. The highlighted yellow line illustrates the mathematical averages of the tests. Other columns explain what the observations were. Checkmarks indicate which test was better, or a win so to speak, for that particular test. At the bottom I tallied the wins. Remember again, this chart was originally just made for my own observation. I would’ve been more careful if I would’ve known I was going to share it at the time.
