So I havnt read the when thing yet but so far I don't see anything that constitutes as research least not in the scientific sense. He claims both shot the same. Doesn't say.anything about a.dual chrono or a gun vice so we can basically throw out any data he collected. He does say the HH is more efficient well it.would be considering the rifling isn't engaging.the FS round so thereby putting less drag on the round. I'll be doing some official tests of the lapco FSR barrel on my trracer as soon as I get the barrel in the mail. Dual chrono and gun vice and video everything we should need.
