bullet sorting...
I just started sorting by bearing length to further reduce my extreme spreads, already anealing, about the only thing I'm not doing yet is trim & point meplats. I am shooting Berger 6mm 105's
I am sorting pills in lots of .003 (I.E. .319-.321 then .322-.324 ect), my question is has anyone ever done any testing to see velocity variation average differences with .002 .003 .005 or .010 ect bearing surface length differences?
bullet seating...
My next question in my quest for low (single digit) ES'S has to deal with bullet seating, ok less jump = more pressure and vice Versa,
To my knowledge there is not a seating die on the market that pushes on or near the bottom of the ogive or nearest the bearing surface, but they all seat from a random point on the ogive (not consistent seating depth)
What are your thoughts?
