So I just got back from the range working up a load with new Lapua .308 brass. Berger 175 HVLD, Lapua Brass (minimal case prep), powder range from 43.6 - 44.8, Varget powder, CCI BR2 primer, Savage 10FCP suppressed.
All the brass oal was around 2.004-2.006 when new. Every case shrunk to about 1.997-1.999. I thought the brass was supposed to get longer not shorter?
