FWIW, in my BalAdv barrel the post firing shoulder measurements came out with a low of 1.1932" for the 70VG w/8208xbr to a high of 1.195" for the 105's and 108 w/LVR. They all started out sized at 1.88" since I didn't have any factory ammo to test with so I went by SAAMI drawing for that initial sizing of the converted Starline 6.5G brass. All of the loads I tested ended up with a case web measurement of 0.441", matching the SAAMI drawing. Pre-firing, the case web was sized to 0.438-ish by the Hornady Custom Die sizer, which I believe is basically a SB/FL die.
