I have been playing around with different ways to make my mini-30's barrel harmonics more consistent. I believe I have come up with a solution but now I am working on a way to make it easier to install to the rifle. I have spent a lot of time at the mill/lathe trying different gizmo attachments. Now is I could only make the add on smaller I may market it. If not at least I had fun doing all the range time trying all of them. This 5 shot group is at 100 yards. I only used reloads also since the .308 bullets seemed to be more consistent.
