I hate you had one bad experience with Leupold, but in 40+ years of mounting scopes on my rifles I have had less than steller results with all the manufacturers of bases and rings. I have a B-78 in 45/70 that I have loaded up to 50,000 psi loads with Leupold mounts and rings and they are very solid. Redfield and Burris use to and may still make bases for the B-78/1885, but both are turn in front and windage screw type rear bases. I remember a friend had a B-78 in 7mm Rem Mag that he scoped using Buehler bases and rings, but that was some years ago. It worked perfectly for many hunts with him for at least 20 years. I hope you find something that works!
Good shooting!
Marcus.
