Has anyone had any issues with factory Federal 300 WSM ammo? I have a Sako that absolutely loved factory 165 partitions. I had several boxes with the same lot number. Used them up and bought several more boxes with another lot number. My one holer is now shooting inch and a half. I tried some factory Accubonds and had to use a rubber hammer to open the bolt. Shiny bolt faces and flattened primers. I sent them back to Federal and they said they were in spec per their computer program for that caliber. The new Partition loads definitely seemed hotter with stiff extraction. Anybody have similar experiences?
