The FX Harmonic Barrel Tuner is Real-and it is Spectacular!
I had the extreme fortune to be in the right place at the right time and was able to get my hands on one of the first Harmonic Barrel Tuners for the FX Impact for some testing.
Prior to this I would run through any new rifle set up with a variety of moderators. The effect of changing from a sumo to a tattoo was to shift the center of gravity of the barrel thus altering its harmonics. I always found that one moderator would win out against the others in terms of group size, and that’s how I would decide which moderator lived on which rifle. I can’t say that I understood exactly why things lined up that way, but I do now.
Other people will describe the science of how and why this works to improve precision, my aim with this video is to add my voice to affirm that the idea of moving a weight forward or backward along the end of the barrel does in fact change the point of impact of the pellet. Interestingly, it doesn’t even just move it up or down. As you’ll see in the video different positions of the way it actually adjusted or shifted where the group was left or right of center. This was not the result of wind in this test, I have done this test over and over and consistently get the same results.
If you don’t believe me, you’ll just have to try it for yourself.
