[QUOTE="hop700, post: 757746, member: 5931"] Out shooting this morning with new Savage LRH 6.5x284. I was looking for a starting point so I tried 3 different loads/bullets. new lapua brass r22 50gr CCI 250 OAL approx. 3.100 (throat of barrel still has .200" free bore). I chose this length so that all bullets would have 100% neck contact (namely the VLD). #1 140gr Hornady SST. shot pretty well, around MOA. Slight extractor mark on some cases. #2 140gr accubond. Shot pretty well, just under MOA Slight extractor mark on some cases. #3 140gr VLD. Only shot twice due to powder residue on outside of case all the way to the base. I do not believe these loads are over pressure. Primers are not flattened and no heavy bolt. I will take a look when I clean the gun to see if there is a burr around extractor slot as I believe this may be the culprit to burnished heads. I stopped shooting the VLD's when I noticed the residue. I would guess that I'm under pressure and not sealing the chamber. Has anyone seen this before? Are the Lapua cases hard (they do come with necks annealed)? Thanks in advance Scott [/QUOTE]
