Well, tomorrow is my shooting day {Wed] so when I'm done I'll have 50 or so cases to experiment with. I'll try a little more cam on the die, turning 180 etc.
However, if ireload is correct about the dies all being out of whack except the RCBS - well, we'll see. I'll probably end up just neck sizing + my 311 M die.
I've noticed one thing - extra hard bolt closing does not help accuracy.
I'll be back
