I saw on a test done by some members where they would shoot at like 100-200 mps? And them 200-300 mps? What is that reading? Some detectors would pick up on lower numbers/readings than others? What do these numbers mean? And I tried to search, but on the mobile site, the win a sti ad is covering the search box. Maybe link me to the answer if it has been discussed before. Thanks so much.
And what guns use what numbers?
