Re: Winchester M 70 BOSS sweet spot help

#I called Winchester and got the Model 70
# manual and the BOSS manual, but not the
# sweep spot chart.

Don't know if this will help, but I have a Browning A Bolt Mediallon
with BOSS in 25-06 Remington, and the owners manual lists the 270
Winchesters sweet spot as follows.

ammo 130 gr. sweet spot 2.5 on the boss micrometer setting.

ammo 150 gr. sweet spot 6.0 on the boss micrometer setting.

Hope this helps.
