I went out and shot my Ruger 77-17 yesterday ,shot 50 rounds of winchester 17HMR V Max and out of 50 shells 7 of the casing split from the neck down about 3/8 of an inch. What do you think this is an indication of ,hot loads from the factory, problems with my ruger,or is this normal? I have never noticed this and I have fired 1000's of rounds through this
rifle.Help me out here tell me should I try to notify Winchester about this problem or Ruger.
