Leupold MK 4 Base question
I'm maxed out at 1,300yds with my current setup. I'm looking for a tapered base and in my hunting around I came across Leupold MK 4 bases which claim: "Bases have a ¼-degree slope for long-range shooting applications" What does this translate to as far as moa? Additionally, any comment on this base? Thanks for the help.
