Man you are good in that you can rely on 2 shots as sufficient samples! I, perhaps foolishly, keep questioning and trying to perfect loads if I can't consistently put 5 in the same ragged hole. But if you keep returning to range and shoot 3 touching as the first 3, that's even better.
Interesting to see this tuner thing evolve. Of course Browning has had the BOSS system for over a decade but I rarely see them in people's hands. I haven't even seen them on recent models. I always wondered how well they work. Great concept if they work. I almost tried one of those rubber grommet type tuners about 10 years ago.
