I'm getting smoke on the case below the shoulders. This occurs on the first two or three shots and stops. This is on a 6.5 creed with 2000 rounds and started at around 1900. Brass is Lapua and only 4 times fired. It only occurs on a cold barrel. Clean or dirty. I have a .243 with 1500 that does this also. Only the first couple. No changes to load or dies. The shiney ring down low is a reamer mark not stretch.
