Curious how y’all use a tuner. A couple days ago, I used on in a 300 yard BR score match to win the match.
In the image, the two bullets below in the sighter red were my foulers and I used ammo from the last match that I shot there a few months ago. I used it to get a rough on where I was on the target. I clicked the POI up based on them. Then I shot cluster 1 with fresh ammo. I noted the vertical but wasn’t ready to attribute it to anything. I carefully examined the flags and didn’t see anything that could have created that vertical. I moved the POI down. Then I shot cluster 2 which is close to the bull but still some vertical. This is where I decided to turn the tuner. I turned it one hash mark in. Then I shot cluster 3. Both were in the 10 ring and grouped together. I moved the POI right and then shot cluster 4. I then clicked one more right and one more down before going to the first record target to the left. After that, the shots tended to stay together. This is how I have used a tuner several times after determining that my preloaded ammo is not in tune. This is after conducting load development with the tuner attached and at the setting closest to the action. Once a great load is developed, I then do a “sweep test” to find the tune window. Once I find the window, I set the tuner in the middle of the window. When the tune falls off, I turn one hash towards the action and then shoot the sighter to see if I’m back in tune. Anybody do it this way?
