I was just looking at my Leupold with its BORS system and 20moa base, and my Horus ACI mounted on my 22-250imp with 20moa base, and it occured to me that the pitch my scope/aci is reading it not true to my bore line?? so how do i mount a ACI with a base with a pitch? i cant do a scope mounted/tube mounted system, or a rail mounted system? any other ideas?
