Thread: A question I am struggling to answer - SMOA Scope, Rangefinder with MOA solution

My Swaro scope is SMOA and and I have a drop chart tested to be correct at 400 and 600 yards.

I could just range a distance & refer to the drop chart (and may have to) but I have a rangefinder I can put a custom ballistic curve in and it will give clicks in MOA (saving a step). The drop chart and curve line up (via Leica app) on inches of drop for distances... but the rangefinder gives an MOA result for the measured distance that doesn't match the drop chart for that distance (the difference at distance adds up (SMOA vs MOA)).

Does this make sense as its the end of week,.. the daughter is visiting from Auckland and the wife and her have been out shopping today so I have a stress headache too.

How do I make a ballistic curve that I can 'load' into the rangefinder so when it says X clicks for 600 yards it matches my SMOA scope? Can it be done or not? If not I'll just EHr range and refer to a chart on the phone and/or printed and stuck on the stock.
