a good group at 600 yards because the SDs could be bad and at 100yrds still shoot
So now I load 3 test loads for each powder weight with the bullet I want to use and
fire 2 then check the SDs , and if they are over 15 I save the 3rd round and pull and
When I find a load in the single digits then I shoot the 3rd round to see if the SDs hold.
Now to improve accuracy I load that load with different bullet seating depths until I
get the best accuracy. and if it shoots 1/2 MOA at 100yards then it will shoot close
to that at 600 or 1000yrds if I do my part and have choosing a good bullet for long range.
There are many advantages in using a chronograph because they give you a history
to go back to if you have to change powder lots.
