I have a 25-06 Ultra. I don't reload so only shoot factory. I'm also looking for hunting accuracy, not benchrest, so am probably satisfied with less than most of the folks on this forum. Have had good success with 100 grain Core Lokts (+/- 1.5" @ 100 yds) and I'm happy with that. Have shot the 120 grain, same ammo, and it is about the same in mine. Surprising that the groups are close since the OAL for the 100 grain is considerably shorter than the 120's. These work for what I need.
