So what happens when you take an FX Impact M3 in .22 cal and wind it up to shoot as fast as it possibly can shooting the heaviest ammo available? Well you get this.....

Great video! Very good information. Convinced me on the utility of the harmonic barrel tuner. Also, those Javelins look good.
Question: is the 1050 fps velocity where those slugs perform the best even before the harmonic adjustment and that's why you shoot at that velocity....or you wanted to shoot at 1050 fps and you needed the harmonic tuner to make sure the slugs perform well at your particular chosen velocity?
For example: JSB's perform best at 880fps. With the harmonic tuner now you can dial in JSB at any velocity (up 150 fps or down 150 fps ) as long as that velocity does not cause fatal flight issues..like wobbling?
Great shooting Chris! Looks like you’ve made harmonic tuning a lot easier. I’m getting about the same accuracy with my .25 Impact X w/PP and NSA 43.5 at 885 to 890 FPS. But it’s taken me hundreds and hundreds of slugs get there. BZ on the tuner!!!

Sorry I don't see it happening. No disrespect. I will buy and try, I hope I eat my words

Thanks Mike! Ya if nothing else, this method saves a TON of ammo! I am lazy when it comes to tuning and I like things being easy. Plus I have interviewed a few high level competitive precision shooters who hand load their own ammo (powder burners) and they will tell you that when you find that perfect primer / powder charge combo that gives you super tight SD / ES with your velocities - DON'T MESS WITH IT! That was an AHA! moment for me in all of this....
Up to this point we have been tinkering with our power wheels and hammer spring settings chasing a harmonic accuracy node, but what we are also doing during that process is ever so slightly changing the harmonic signature of the platform by changing the velocity. The harmonic tuner isolates JUST the barrel harmonic aspects of the platform. During this discovery process I have become a disciple of SINGLE VARIABLE TESTING!

Did you see any drift in harmonics with temperature change?
Curious, is the tuner attached the barrel (CF sleeved barrel) or the inner or outer sleeve? Maybe in the Near future you can break it down for us to see.
