I have a 6.5 300 wby mark 5 I have put about 120 rounds down the barrel. I have cleaned it diligently after every 20 or 30 shots. Now out of the last 10 or 15 shots I have been getting flattened primers and slight ejector marks on case heads with 2 different factory loaded ammo 140vld and 127gr lrx bullets and chronograph speeds around 3640 or so which is about 100fps faster than advertised. What is going on? I don't know if I should continue to shoot it until I find some answers. Any suggestions would be greatly appreciated thanks
