Thanks for the info. Your COAL of 3.43 is right in line with Andrew Massi's calculated COAL of 3.479'ish for the 156 Berger.+1 on the 30-06 Lapua brass, don't worry about the short brass its no problem at all. Only problem i could see potentially is a donut necking up.
Other than that its a great cartridge.
My reamer is set up to run the 140 VLD at just above the neck shoulder junction with a .296 neck chamber gotta turn these brass but thats fine for me because I wanted the best brass available.
C.O.A.L is 3.43 if I remember correctly.
