Speer Gold Dot Chrono Data Both the 115 grain and 124 grain were used at all three distances, so there are three strings of five shots to consider, for each. Admittedly, a sample of five is perhaps not as good as a fifteen sample in one bite but ... the results will still I feel prove valuable. String velocities are rounded up or down to get rid of decimal point. Muzzle Energy (ME) is based on the average velocity (Av Vel)

Sorry - just noticed on the printout ... second shot in this first series failed to register and showed as error so - a sample only of four.

These results appear exceptionally good ...... let's combine some figures and see what we finish up with (apart from SD - which I am not stopping to calc on the fifteen - no, fourteen sample!). Low vel overall - 1053 fps Hi vel overall - 1078 fps Average (of averages) - 1063 fps Max spread - 25 fps. (in fact sample #2 spread) Average ME - 289 ft lbs. I am impressed with these tight figures overall .... and energy levels like this from the R9s short barrel are very useful.
