Went out to put a couple rounds through my lapua today. I noticed slight ejector marks that I had not noticed working this one up. I'm shooting 40.6 grains of H4350 with 130 berger hunting bullets. They are just off the lands with a oal of 2.78" shooting a 26" Brux barrel. I may need to back off and work up again? I was around 85° and humid today.
