You'd be doing yourself a disservice if you didn't at least give it a go, following the instructions to the letter. The barrel tuning ability is legit. I had a QUE tuner on a Remington 700 6mm. Works on the same principal as the Browning BOSS. By systematically adjusting the tuner, I was able to take a rifle that was previously cable of no better than 1.25" groups and tune it to shoot in the .5" range with the same load.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land. 2 Chronicles 7:14
