    I was able to try adjusting the tuner to improve my rifle's groups today. Found some interesting results. As always, it's uncertain how these results would hold over large sample sizes and from week to week. But today, I shot my best group ever (~1/8 MOA 5 shot).

    Here's a quick tuner run on paper at 200m with a different bullet. This time the 112 Barnes match burner 6mm.

    I do appreciate how I can quickly get to a setting that is good. At the cost of shooting these centerfires, I have no desire to fire hundred round tests to find a setting.
