Re: Moa or Mil, which is easier to learn?
Sober-
I am not given to conjecture much. More a shooter than a thinker
It has been my experience in shooting, scoring and coaching that most misses come from shooter error NOT involving .47". Most times the error is in ranging the target, not the 20" at 1000 you refer to, afterall most have a solid comeup chart with 'did hit' data at their disposal.
Next biggest error is an incorrect wind call. Best example of this that takes your .47" out of it is F-TR matches. We dail a base wind on and then shoot the rings. No conversion of wind speed to MOA correction but see the spotter compensate for the wind and shoot again. The fly in the ointment is failure to catch that subtle wind change.
Not to open another can of worms but I credit a failure to catch the subtle wind changes at Long Range for those unexplained 'flyers' some want to blame rifle cant for causing.
I'd would be so bold as to suggest that even the much vaunted got to make that first round hit tacticool comp shooter has far more misses than hits due to wind making them a bitch, not the .47"
Quick review-
for range I have a shot data comeup chart, not some computer conjectured might hit data. No 20" error there.
Wind error, for me to have a 20" due to the difference between 10" and 10.47" just how hard is the wind blowing???
