This is the truth! You may get lucky and find something that both rifles like, but not likely. My friend has a model 94 that loves Remington Core Loc 170gr, and 190gr silver tips. mine does not like either. Win 150 or 170 sp was the ticket for mine in factory ammo before Lever Evolution came out. I'm still testing those.From my experience, one of the rifles will "prefer" a different ammo than the other.
And, also from my experience "you" are a significant part of the equation, too.
