I'm trying to get my head around moa's etc on the hawke chairgun program so perhaps someone out there can teach a numpty about the obvious I'm not getting!!

Ok its a rapid.22, pushing 34.48 ftlbs, 847.3 ft/sec, bis mags at 21grains, 45 yd zero on x6mag, wearing a viper 4-12x44 scope.
The scope is 1/8th " adjustment at 100yds per click, so in the MOA/Clicks box I've entered 1/8th @100yds.
I haven't yet worked out the bc of the pellet, until I do, I'm just using the default BC.

What I'm trying to workout from the table is how to read the turret marks. For example @70 yds according to the table is 4.56 Moa or 38 clicks. That corresponds with the no9 marker on the turrets.
If I go to 4.5 on the turret markins that corresponds with 18 clicks.
Obviously testingand a logging the poi with the turret markers will be the most accurate way to calibrate the turret markings. But an ouline to understand it would be very helpful.

Thanks
