Fine tuning COAL.

as much as bench rest is to fcass don't for a minute believe accuracy in requirements are more or less, be it you shoot em all quick or wait for pitts to mark the individual shots, I know if my rig isn't shooting with a 99% tuned round going in it, I know my wind call will be off in any direction unknown, if its tuned right it will shoot as good as the mind pulling the trigger, before each match if possible I will test and re test every possible criteria until I know its at its best. getting back to seating depths start jammed and work back .005 increments , re evaluate, and pick your best. retest again, re evaluate, and then work in .002 changes and that should put u close, then re evaluate that 3 more times that should get real close, then if that don't help try going to the bar and re evaluate what your doing.

About how many rounds does it take to call a load good typically? sounds like a lot of rounds down the barrel before you would call a rifle tuned.

A .250 tune with ES of 16 with a dasher 10 shots . 10 more shots to get the ES to 8 That is a tune but not one off the point of aim. You have to find the point of aim tune that shoots in the wind condition your trying to shoot in Then you can verify at 600 .
Your must have the case prepped and the capacity the same . Larry

Larry, to understand correctly, you say 20 rounds to find a load with an ES of 8 that shoots under .250"?
Is there any way you could post some pictures of what a typical load work-up or tuning session is for you to see how it all develops into a tiny and consistent grouping load ?

Thanks.

We have some on U tube and some on Bostrom gun smith . Got a new dasher going to test this week Will video it for you. The next test will have the cases fully peeped That is when you see the ES drop And we
will tune off the point of aim .
Case prep will be separate Larry
