Hi all... just joined the site and I need to ask if anybody can help me find the "factory sweet spot" for my Browning A-Bolt w/BOSS in 300 WSM and with 180 gr. XP3 Winchester Supreme ammo. I don't want to have to shoot up $150 in ammo to zero my rifle for the XP3s.

Unfortunately, Browning does not list the factory sweet spot for that round. Has anybody herewith an A-Bolt w/BOSS tried to dial in the 180 gr. XP3 bullet in 300 WSM. If so, pls relate your experience.

TIA, cd.
