taper base

If I was going to make a tapered scope base how would you figure out how much to taper it.I shoot a state arms 50 but the most moa base he makes is a 21moa and I want a 30 or 40 moa base.

    A taper of 0.001 in 4" will give you 1" at 100yds.

    For a 40moa taper, if they have a 21 base, you need 19 thou difference over a 4" section of the base.

    Barrett makes a very clever scopemount that attaches to any Weaver/Picatinny type base, that is adjustable for taper.

    I have one on my AR-50, and combined with a B&L 10x Tac, and set so the 100yd zero is at the bottom of the elevation range, it gives me a full 145 moa of "up".

    IIRC, 0.0058" taper/inch = 20MOA

    so 0.0116/inch should get you 40MOA
