Re: How do you work up a load the right way?
Well it depends on your ammo use goal.
- one of my first considerations is does it need to be magazine length or under or is single loading of over mag length bullets desired for max accuracy.
-if I desire a magazine compatable load I'll load about 8-10 thousandths under mag length and walk up the powder charge. Tune for the best and then adjust seating depth depth shorter in 10 thousanths increments until I find the best of that.
-then you can tune for neck tension; 0.001, 0.002, 0.003, or 0.004" tension. For this to work you need to be consistent with cleaning the carbon and lube out of the inside of the neck or your wasting your time. I use a bore brush with a wrap of steel wool to remove the carbon. it may be overkill and it might not.
I'm still learning the precision accuracty game from a lot of folks here but those are my findings.
another thing that my experience has show me; either jam a bullet into the lands a few thousandths or get at least 10 thousanths away. If I'm less than that away the variance in ogive distance to the lands is enough to cause my ES/SD to jump. This is my experience in my rifle, other guys might disagree in their experience with their rifles. At 300 yards my 0.005" jump loads were more than double than my 0.010" jump. I'm thinking this is all about the consistency of the build up of the pressure curve.
