Hi folks…

I took my O/U 93x74R shooting today for the first time in about 3 years, (changed house, changed job, changed career, moved across the continent…) and I was horrified to discover that my bottom barrel chamber is spitting out cases with cracks in the neck!!!

These were brand spanking new factory rounds, never fired, never reloaded. Granted, they have also been sitting in my safe for a few years, but they are still "new" factory ammo…
What does this mean? I'm fearing the worst, that the chamber is pitted…???

The barrel is shooting beautifully, 1" groups, exactly on point of aim, but its treatment of the cases is unacceptable.

Does anyone have any ideas of why this is happening and what can be done to solve this problem?
Any comments or suggestions would be appreciated.

Many thanks,

Pete.
