I have gone down the 10/22 worm hole a bit.
On my way down I saw a post about this barrel tuner.
I said to my self. Dang I have a few of those laying around in my archery gear for stabilizers etc.
so I threw one on my semi modified 10/22
After a few 25yd groups and 50yd groups and sliding it up down and around I am impressed. I found a place or two I think that the groups are really better. I’m kinda excited to see if it’s placebo or factual. Different ammo and velocity’s.
Any way, has any one tested this thing or keep one on a centerfire that you know works for sure?
In my case a .223 varmint contour barrel. Shooting heavy pills.
