Short story, we can consider this aspect = adding the brake increased group size. Tuning it brought group size back to about normal. So if a person wants a brake, it brakes as intended and has tuning ability to nullify the changed harmonic causing group size increase. For factory ammo shooters, it does provide a tool.
Long story, from what I saw it surely warrants more ammo, time, and comparisons.
JP 22 barrel, medium contour.
I was so focused on checking grouping I forgot about the brake function. After a few shots I was thinking it was shooting noticeably more smooth and tame than usual, it was very nice. Then it dawned on me, oh yeah, the brake. There is considerable reduction in recoil from usual. The brake feature meets objective.
The grouping.... this is the first time I have put anything on the end of this barrel aside a thread protector. I have an SJC brake I recently picked up that I can put on to check how it effects grouping due to harmonic changes.
I would also like to see what can be tuned in via in between the dial test points and going further out on the dial.
Seems as I dialed out, the nodes of peaks started to get bigger and valleys (small grouping) were trending smaller.
If I were to measure group size via more appropriate center to center, that 1 1/4 group would be 1. Thats at 120 yds, sub MOA.... about MOA at the larger outside to outside measure.
(I typically measure outside because my preference to underrate)
