Ha ha... Yep. I think you are right. Just never messed with a boss. They always seemed weird to me.. But hey, some guys like 270's too....
I have a 5 digit sm Classic in a 338 with boss system I haven't shot it but from what I gather you shoot it and move the boss until the groups tighten if you go the wrong way you wasted ammo but here's the thing the instructions don't tell you which way to go first. I'm guessing I'm overthinking it ..
Winchester at one time listed suggested starting points with the BOSS for common factory loads. Maybe Browning still does.
I always wanted to try the BOSS system until I found out that they needed to be cleaned more often than I wanted to if they were to continue to work. Then I figured out that I could tune barrel harmonics by adjusting the ogive to rifling distance in my handloads and achieve the same thing without the goiter on the end of my barrel.
They are loud. I usually help with my gun club's annual sight-in days. We have covered ranges. I leave the area when I see one approach. They will knock dust off the overhead beams when fired.
