Comments on: Wave Pattern POI — How Barrel Tuners Alter Point of Impact

So…does a particular position on the sinusoidal curve (i.e. high/low POI) correspond to the best grouping? I’ve seen a few of these types of targets, but never heard whether a particular position on the curve actually corresponds to the best grouping.

I totally agree with the Editor’s Note. POI is different for each linear position of the tuner. No surprise.

What we need to see are 3-5 shot groups at each linear position of the tuner. That would tell us what we want to know; what is the most accurate position for the tuner, or if there really is one.

I’m strictly guessing but if I remember what I’ve read and if I understood it the three very low impacts could be good. I think you want the points either at the very top or the bottom because those are where the barrel is reversing direction as it whips up and down, but the peaks on the high side are less obvious in these shots.. It has to hit a zero vertical velocity to change direction, so should give more consistent results there. Reminds me of shooting a sporting clay at the top of the arc to take vertical velocity out of the picture. Don’t know if it’s right or not!

I would like to see a 5 shot group before the start and after to verify load performance.
