So took a go at testing a Tuner (ATS) for the first time. I started with a .5 ish moa load and figured let’s see if we can tighten this thing up. First string was for baseline, no tuner, just thread protector. Then i started the test with .2 increments as we moved on. After the top row, I went back to the two best that seem to be one holers, they did not repeat though. I then went back to .2 grain increments again and the first three shots look good so I let two more fly. Decided to make a .1 increment change and let five more fly and I think this might be the best area for this load/rifle combo with the tuner, although not a fan of the POI shift. I will load up another 50 and maybe do some 10 round groups and see if a bigger sample size does any difference or shows me any difference between using the Tuner and not. Then again, this may be the best this Shilen barrel can do. Feel free to offer up your thoughts or advice if you have experience with these things.
