    So, yes, the 75 GDs are a bit faster in my tests than the 75 TAP SBR. Still almost 100fps slower than the referenced test.
    Your numbers are very similar to mine. I got an average of 2170 out of a 10" SCAR and 2280 out of an 11.5" BCM with the TAP SBR. Those measurements are at the barrel using a magnetospeed. While that is on average 25-50 fps slower than most other 75 grain loads through those guns, the TAP SBR is noticeably quieter and softer shooting through a SF 556 RC2. It is also very accurate. I'll take those trade offs in a gun that will be used to engage targets at less than 100 yards; I bet they won't notice the difference after a center mass or head shot.
    I like my rifles like my women - short, light, fast, brown, and suppressed.
