I find ranging by shots to be very inadequate.
I guess im not well informed, but i can say this much.
Years ago before lazer rangefinders were available many people didnt have rangefinders. But somehow many were still very successfull at long range hunting.
Today we not only have excellant compact rangefinders but we also have computer
generated programs to help produce accurate data sheets.
But, for best results most of us realize the data at least (should) be confirmed by
shooting. And even then on some days during some conditions the data could be
slightly wrong. Go to a 1000 yd rifle match where the distance will be exactly the
same from match to match. Yet the very best shooters will take sighter shots before shooting their record target.
None would dare just dial in the information and then just wait for the record target to be raised.
The problem as i see it is it really isnt all that difficult for most of us to become (fairly) profficient at shooting reasonably long distances.
And that frankly dosent sit well with everybody.
